Case Study 14.2 🔬 Deep Dive: Sundown's Second Proposal

📜 From the Field

The Reyes–Whitfield wedding is a Tier 3 illustrative composite. Sundown Provisions, its pricing structure, and every figure below are constructed. The structure — a service charge on a distributed basis, tax on food only, a flat field-kitchen line, and a proposal that quietly omits four things — is drawn from how catering proposals are actually built.

This is the deep-dive case. It is arithmetic-heavy on purpose. If you are on the 🏃 Fast Track, read the two summary tables and the section headed "The Cheaper Dinner Is the Better Wedding" and move on.

Where We Are

Chapter 12 selected Sundown Provisions on a loaded-rate comparison: $120.09 against Harvest & Thyme's $120.60 and Copper Kettle's $123.37 — 2.7% apart, with Sundown cheapest all-in and, more importantly, the only one of the three who had cooked at a raw site more than twice.

Their proposal came in at $14,521** against an **$11,800 allocation. Sundown's sales lead, Marguerite, said the sentence this case exists to test:

"Eleven eight is workable if we go family style."

Chapter 13 then blew a hole in the budget: the rental order landed at $17,409 against $10,790 allocated, and $3,819 of the gap was closed by re-cutting the Chapter 6 allocation.

And the re-cut took $900 out of catering.

Act One: Putting the $900 Back

The rebuilt allocation showed catering at $10,900. Nobody decided that. It happened because catering was a large line and large lines are where a re-cut lands.

🚪 Threshold Concept: a re-cut is an allocation decision, and it is governed by the same ranking as the first one

Chapter 6 built the allocation from the couple's forced ranking. Food is ranked first. The party is second. Photography is third. Stationery is the thing they are most relaxed about.

A re-cut that takes $900 from the first-ranked category to fund an infrastructure overrun has quietly reversed the ranking — and it did it in a spreadsheet, on a Tuesday, without a conversation.

The rule: any change to an allocation is a change to the claim about what matters, and it goes back through the ranking.

The $900 came back. It was taken from **stationery** ($700) and from the design contingency ($200).

Catering allocation: $11,800.

⚠️ What this hands to Chapter 19: stationery is now $700 lighter, on a line that was already the smallest in the budget. That is the correct outcome — the couple said stationery was what they cared least about, and the budget now says so too. But Chapter 19 has to live inside it, and place cards for 100 people are not free.

Act Two: Reading the Proposal Line by Line

Here is what Sundown actually sent, decomposed.

💰 Run the Numbers: Sundown Provisions, original proposal — 100 guests

Line	Basis	Amount
Dinner — plated, three courses	$94.00 × 100 | $9,400.00
Passed canapés — 3 items	$12.00 × 100 | $1,200.00
Cake cutting, plating, coffee and tea	$3.75 × 100 | $375.00
Food subtotal		$10,975.00
Service charge, 20%, distributed to staff	20% of food	$2,195.00
Sales tax, 7.75%, food only	7.75% of food	$850.56
Field kitchen and equipment transport	flat	$500.00
TOTAL		$14,520.56
Allocation		$11,800.00
Over by		$2,720.56

Loaded rate check: $10,975 × 1.2775 = $14,020.56, plus the flat $500. Dinner alone loads at **$94 × 1.2775 = $120.09 — which is exactly the figure Chapter 12 compared, and it is a dinner rate, not an all-in rate. That distinction is the whole of Act Three.**

What is not in it

Run §14.2's four eating moments against the proposal and the omissions are structural rather than careless.

And one omission that is not an eating moment at all:

Vendor meals: zero. The Chapter 12 vendor matrix shows 12 outside crew on site through dinner — two photographers, a videographer, five band members, two restroom-and-site staff, and the officiant's driver. Sundown's own nine feed themselves out of their labour line; the other twelve do not.

🚨 When It Goes Wrong: the proposal that is under budget because it is under scope

A caterer's proposal answers the question you asked. If your RFP said "dinner for 100," you will get a price for dinner for 100, and it will be a good price, and it will not be what your wedding costs.

Sundown's proposal was over budget by $2,721 while also being $1,460 of food short of the event. Both things were true at once, and only one of them was visible.

The RFP in Chapter 12 asked for the whole day. It did not ask for a line-item response, and so it did not get one.

Act Three: The Brief

§14.2 says to brief constraints and priorities, not dishes. Chapter 12's RFP had the constraints. It did not have the priorities, and it did not have a number.

Here is what went back to Marguerite.

📋 The Planner's Script: the second brief

Marguerite —

Thanks for this. Two things: the structure is right and the number is wrong, and I don't think those are the same problem.

The number. I have $11,800**, all-in, everything with your name on it. Not $11,800 plus service charge, plus tax, plus the kitchen line. Eleven thousand eight hundred dollars leaving their account. Can you build to that?**

What it has to cover, and this is where I think we've been talking past each other:

• Passed canapés — and I want to go up, not down. Cocktail hour is seventy minutes on a lawn with a bar and no chairs. Three items at three pieces a head isn't enough. I want four items and I'm budgeting five pieces a guest.
• Dinner, family style.
• Twelve vendor meals. They weren't on the proposal.
• Something at half nine. Hand pies, sliders, whatever you'd do. Sam's phrase in the vision session was "still there at midnight," and the party is ranked second of everything at this wedding.
• Cutting and plating Alicia's aunt's cake, plus coffee and tea.

What I care about, in their order: food is ranked first of twelve. The party is second. Nothing else on this list is close.

What you've got to cook in: you know the site. Marquee kitchen, propane, no gas, the doorway, September.

So here's the actual question. If I give you roughly six thousand for dinner and tell you it's family style for a hundred in a field in September and these people care more about food than about anything else — what would you cook?

Don't cost my list. Tell me yours.

Marguerite's reply came back in two days.

"Six thousand is sixty a head and at sixty you get one main, not two. I'd rather do one main properly than two badly, and honestly at a raw site the pork shoulder is the better dish anyway — it goes in at eleven, it comes out at six, and it does not care that it sat for forty minutes.

So: slow-roast pork shoulder with the cider and the mustard, a bowl of the green beans with the almonds — no, scratch the almonds, see below — the roasted squash with sage, the potato and leek gratin, the September tomato and bread salad while there are still tomatoes, and the bread and cultured butter. Family style, everything on the table at once.

Four canapés at seventeen. Hand pies at half nine, one and a half a head, six dollars. Vendor meals at thirty, they get the same food on a plate. Cake and coffee, three seventy-five as quoted.

One thing about the field kitchen line. Five hundred is three hundred for the marquee and two hundred for the propane rig. You've already rented me a marquee — I saw it on the rental schedule. So that's two hundred.

And I need to talk to you about the nut allergy, because family style is the worst service style in the world for an allergy and nobody ever says so."

Act Four: The Revised Proposal

💰 Run the Numbers: Sundown Provisions, revised — family style, 100 guests

Line	Basis	Amount
Dinner — family style: pork shoulder, three sides, salad, bread	$60.00 × 100 | $6,000.00
Passed canapés — 4 items, 5 pieces/guest	$17.00 × 100 | $1,700.00
Late-night hand pies — 1.5/guest	$6.00 × 100 | $600.00
Cake cutting, plating, coffee and tea	$3.75 × 100 | $375.00
Vendor meals	12 × $30 | $360.00
Food subtotal		$9,035.00
Service charge, 20%, distributed		$1,807.00
Sales tax, 7.75%, food only		$700.21
Field kitchen — propane transport only	flat	$200.00
TOTAL		$11,742.21
Allocation		$11,800.00
Under by		$57.79

Saved against the original: $2,778.35.

And what the wedding gained in the process:

🔍 Why Does This Work? The saving did not come from cutting food. $1,460 of food was added.

It came from three places:

Source	Amount saved (loaded)
Plated three courses → family style, one main	$4,343.50
Field kitchen line, marquee already rented	$300.00
less food added back (canapés, late night, vendor meals)	−$1,865.15
Net	$2,778.35

The dinner line fell 36% and the food on the table went up. That is not a trick; it is what happens when three courses of individually plated protein become one slow-roasted shoulder and four bowls, and when the service charge and tax that ride on top of $9,400 ride on top of $6,000 instead.

Note what carried the saving: the 27.75% that loads onto every food dollar. Every $100 cut from the menu is $127.75 cut from the invoice. It is also why every $100 *added* is $127.75, which is why the canapé increase cost $638.75 and not $500.

Act Five: What the Service Style Bought

The money is only half of it. Here is the other half.

💰 Run the Numbers: service duration at Wildrye, 13 rounds, 100 guests

The site constraint: Chapter 13 moved the plating area out of the dining tent and into a 20 × 20 marquee. The run from the marquee to the farthest table is 70 feet. Chapter 11's floor plan has it.

Plated, three courses, 5 servers (1:20):

• 13 tables ÷ 5 servers = 2.6 tables each
• × ~4 min per table = 10.4 minutes theoretical per course
• Realistic multiplier, with a 70-foot run and a field kitchen: 1.6–2.0× → 17–21 minutes per course
• Three courses + clearing between: 60–75 minutes of service

Family style, 5 servers:

• 13 tables × 4 vessels = 52 vessels (main, two sides, salad; bread pre-set)
• 2 vessels per trip = 26 trips ÷ 5 servers = 5.2 trips each
• × ~75 sec per round trip = 6.5 minutes theoretical
• Realistic at 1.6–2.0×: 10–13 minutes
• Plus a replenishment wave at ~20 minutes: +6 minutes

Everything on the table in 13 minutes instead of 75.

The block, built

Dancing: 8:45 to 10:30 — one hour and forty-five minutes.

Now run it with the plated dinner Sundown originally proposed. Service goes from 13 minutes to 60–75, and the eating time does not compress because the courses arrive in sequence:

🚪 Threshold Concept: the binding constraint was never the caterer

The amplified-music curfew is 10:30 p.m., written into the Wildrye contract at §9 and audited in Chapter 8. It has been sitting in the file since month five.

Every minute dinner runs long is a minute taken off a party that ends at 10:30 no matter what. Move the first dance from 8:45 to 9:35 and the couple lose 48% of their dancing — at a wedding where the party is ranked second of twelve and where Sam's imagined moment involves midnight.

The family-style decision was made to save $4,343. It also bought fifty minutes of the thing they said they wanted second-most. That convergence is not luck. It is what happens when the service style is chosen against the priorities instead of against the aesthetic.

Act Six: The Allergy Nobody Wants to Talk About

Marguerite's last line was the important one. Family style is the hardest service style in the world for an allergen, and it is the one most often chosen by couples who want a relaxed dinner.

Here is the dietary matrix.

📐 The Reyes–Whitfield dietary matrix — 11 of 100

Guest	Table	Requirement	Category
Marisol Vega	6	Tree nuts — anaphylactic. Carries an auto-injector	Allergy — medical
Daniel Okonkwo	6	Shellfish, moderate	Allergy — medical
Ines Reyes	3	Coeliac — diagnosed	Medical
Kevin Marsh	11	Gluten — preference	Preference
Sofia Whitfield	9	Vegan	Preference
Ariel Chen	9	Vegan	Preference
Tomás Reyes	4	Vegetarian	Preference
Grace Adeyemi	4	Vegetarian	Preference
Nadine Hollis	12	Vegetarian	Preference
Yusuf Demir	8	No pork	Religious
Hana Whitfield	2	Pregnant — no soft cheese, no undercooked	Medical

11% — squarely inside the 8–14% band from §14.3.

Why family style makes it worse

🧩 Productive Struggle

Before reading on: name the two mechanisms by which family style endangers Marisol Vega that plated service does not.

Give it a genuine minute.

The two mechanisms

1. The serving spoon. Four vessels on a table, eight people, one spoon each — and within ninety seconds a spoon that has been in the green beans is in the gratin. A nut-free dish becomes a nut-exposed dish through no fault of the kitchen. Plated service has no shared utensils.

2. The platter is anonymous. A plate arrives for a person. A platter arrives for a table, and nobody at that table knows what is in anything. Marisol cannot ask a server, because the server put the bowl down and left. She has to either interrogate every dish or eat nothing, and at a wedding, in front of seven people she half-knows, most guests eat nothing and say nothing.

There is a third, smaller one: guests pass platters, so a dish that was placed at the far end of the table arrives having been handled by six people.

The resolution

📋 The Planner's Script: the allergy call with the caterer

"One of the guests is anaphylactic to tree nuts. Marisol Vega, table six. She carries an injector.

Family style worries me here — the shared spoons and the fact that nobody at a table knows what's in a bowl. So I'd like to ask for two things, and tell me if either is a problem.

One: can the whole menu be nut-free? Not nut-free-for-her. Nut-free. You mentioned almonds on the green beans — if that comes off, is there anything else? Because if the entire spread is clean, the spoon problem disappears and I stop worrying about it entirely.

Two: she gets a plated portion as well, marked, hand-delivered, so she has something she knows is hers even if she doesn't want to reach into a shared bowl. She can eat off the platters or not, her choice — but I don't want her sitting there deciding.

And I'll want the chef to know her by name and table, not just 'nut allergy at six.'"

Marguerite took the almonds off and the menu was built nut-free. It cost nothing. She noted, correctly, that the pork rub has mustard and the gratin has dairy, and asked whether either was a problem — they were not.

🔬 Deep Dive: why "make the whole menu clean" beats "manage the exception"

An exception has to survive a chain: the sales file → the BEO → the kitchen brief → the plating pass → the correct server → the correct seat. Six handoffs on a night when the kitchen is a marquee and the lead is fourteen hours in.

Removing the allergen from the menu removes the chain. There is nothing to get wrong.

When it does not work: when the allergen is structural — a dairy allergy against a menu built on gratin and butter, a gluten intolerance against a bread-forward spread. Then you are back to managing the exception, and the four-part protocol of §14.3 is the whole of your defence.

The general form: prefer eliminating a failure mode to managing it, and only manage it when elimination costs something real. The almonds cost nothing. That is not always true.

And the rest of the matrix

• Two vegans and three vegetarians. Family style solves this well: the squash, the gratin (made without stock), the tomato salad, the beans, and the bread are a complete meal already. One additional vessel — a white bean and September vegetable braise — goes on tables 4, 9, and 12, which is where the seating chart puts them.
• Coeliac. Ines Reyes gets a plated portion. Kevin Marsh, who avoids gluten by preference, does not, and is not told there is a difference — he eats the gratin and the squash and is fine. §14.3's distinction, applied.
• Yusuf Demir. The single main is pork. This is a real problem and it was created by the $60 brief. Sundown adds a portion of roast chicken to table 8, plated, at no charge, because it is one plate. Had there been three guests, it would have been a menu decision, not a favour.
• Hana Whitfield. No action required beyond the kitchen knowing; nothing on the menu is soft-ripened or undercooked.

🚨 When It Goes Wrong: the seating chart and the dietary matrix are the same document

Every line above resolves to a table number. The vegan vessel goes to tables 4, 9, and 12. Marisol's plate goes to table 6, seat 4. Yusuf's chicken goes to table 8.

If the seating chart changes in the last week — and it always changes in the last week — every one of those is now wrong, and nothing in the process will tell you.

The rule: the dietary matrix carries table and seat, it is regenerated from the seating chart rather than maintained alongside it, and the version that goes to the caterer is dated. Chapter 26's production book has one copy of this, not two.

The Cheaper Dinner Is the Better Wedding

⚡ Quick Reference: the whole case in one table

	Original proposal	Revised
Dinner	$9,400 plated, 3 courses | **$6,000 family style, 1 main**
Canapés	$1,200 (3 pieces/guest) | **$1,700 (5 pieces/guest)**
Late night	—	$600
Vendor meals	—	$360
Cake service	$375 | $375
Field kitchen	$500 | **$200**
All-in	$14,520.56** | **$11,742.21
Against $11,800 | **+$2,720.56**	−$57.79
Service duration	60–75 min	13 min
First dance	9:35	8:45
Dancing	55 min	1 hr 45

$2,778 cheaper, $1,460 more food, and fifty more minutes of the party.

None of it came from negotiating a price down. Sundown's rates did not move. It came from asking for a different product — and the product was different because the priorities were stated, the constraints were stated, and a number was stated.

The Two Things This Case Did Not Solve

1. $57.79 is not headroom.

The guarantee is due 14 days out. It will be set at confirmed-yes plus 2–3%, and the working forecast is 100.

Marginal cost per additional guest: $86.75 of food ($60 dinner + $17 canapés + $6 late night + $3.75 cake service) × 1.2775 = **$110.82.**

**The $57.79 of headroom covers half of one guest.** If the guarantee lands at 103 — entirely plausible — catering is $274.68 over.

That is not a catering problem. It is Chapter 7's contingency, which after the generator change order is already below half. Flagged, quantified, and carried into Part V.

2. The RSVP chain now has a deadline it did not have before.

Sundown's guarantee is −14 days. Work backwards through everything that needs the final count:

The invitation timeline in Chapter 19 must produce an RSVP deadline no later than −28 days, and Chapter 19's budget just lost $700. Both are now constraints rather than preferences.

And a third thing, smaller and sharper: Aunt Bernarda's cake. Sundown will cut and plate it — that is in the $375 — but their contract excludes liability for food they did not prepare, there is no refrigeration on site, September afternoons at Wildrye run warm, and the cake needs a table, a knife, a delivery slot in the load-in, and a named human who cuts it if the couple are dancing. None of that is catering's problem and all of it is the planner's. Chapter 27.

Discussion Questions

1. The re-cut took $900 from catering without anyone deciding to. Design the control that prevents this. Be specific: what document, what field, what triggers a review?

2. Marguerite's original proposal omitted vendor meals and late-night food entirely. She is a good caterer. Why did she omit them, and whose failure is it?

3. The brief said *"I have $11,800 all-in. What would you cook?"* — which gives the caterer the budget before they quote. **Argue that this is a negotiating error** that guarantees the caterer prices to the ceiling. Then argue the other side, using this case's outcome as evidence. Where do you land, and does your answer change for a $60,000 catering budget?

4. The case treats the 50 minutes of extra dancing as a benefit that fell out of a cost decision. Reverse the analysis: suppose family style had cost more than plated. Would you still recommend it here? Compute what it would have to cost before you changed your mind, using the couple's ranking as the standard.

5. The nut allergy was solved by removing almonds from one dish. Construct the case where this approach is wrong — where making the whole menu allergen-free costs the other 99 guests something real. How do you decide?

6. The dietary matrix resolves to table numbers and the seating chart changes in the last week. §"When It Goes Wrong" says the matrix should be regenerated from the chart, not maintained alongside it. What does that mean in practice for someone working in a spreadsheet? Design it.

7. Yusuf Demir cannot eat the single main because the $60 brief bought one protein. Sundown absorbed one plate of chicken as a favour. **At what number of no-pork guests does the menu itself have to change**, and what does that do to the $6,000?

Mini-Project

Rebuild a catering proposal you did not write.

Obtain a real catering proposal — from a caterer, a venue, a couple, or a published sample. Then:

1. Decompose it into food subtotal, service charge, tax, and flat fees, and compute the true all-in per-head. Almost no proposal presents this.
2. Run the four eating moments against it. What is missing? There is always something.
3. Count the vendor meals it assumes against a plausible crew list.
4. Convert its staffing line into minutes, and build the dinner block.
5. Rewrite it as a family-style or hybrid proposal at the same all-in cost, and compute the change in service duration.
6. Write the brief that would have produced the better proposal the first time.

Deliverable: the two proposals side by side, the two dinner blocks side by side, and a one-page brief. This is the single most transferable exercise in Part IV.
