Chapter 23 — Instructor Material

Teaching Notes

Chapter: 23 — Hospitality and the Guest Experience: Service Recovery, Reviews, and the Second Visit Sits between: Chapter 22 (front-of-house mechanics) and Chapter 24 (revenue management). Prerequisites students must actually have done: Chapter 1 (prime cost, contribution), Chapter 2 (the capture requirement), Chapter 14 (the Friday night), Chapter 21 (the retention bundle), Chapter 22 (sequence of service).

What this chapter is for

This is the chapter where the book's third theme stops being a sentiment and becomes a revenue model. Students arrive at it expecting a soft chapter — "be nice to guests" — and the teaching job is to break that expectation in the first fifteen minutes and never let it back.

The chapter's method, which is more important than any of its numbers: you can almost never measure the return on a hospitality decision, but you can always compute the break-even. Every major argument in the chapter is built that way — a comped entrée breaks even at 13.1%, a $77 recovery at 1.2%, a year's comp budget at 0.63% of the guest base, review responses at 0.72% of revenue. If students leave with only one transferable skill, it should be this: when you cannot estimate a return, compute the bar it has to clear and ask whether you believe the effect is at least that big.

The three misconceptions to attack, in order

1. "A comp costs the plate cost." This is nearly universal and it is wrong by 3.4×. Students say the Hearth Chicken comp costs $8.52. It costs **$29.00**, because the food was made and eaten either way and the only variable the comp decision controls is whether revenue arrives.

The demonstration that fixes it permanently: put the two columns on the board side by side (charge: revenue $29.00, cost $8.52, contribution +$20.48 · comp: revenue $0, cost $8.52, contribution −$8.52) and make them subtract. Do not explain it first. Let them find the $29.00.

2. "Frequency is the marketing department's job." Students reflexively route "we need more business" to Chapter 27. Figure 23.2 is the counter: at a fixed guest count, a tenth of a visit per guest per year is $14,108, and buying the same money through reach costs $98,223 with a three-year payback. Make them state out loud which department is accountable for visits two, three, and four.

3. "Hospitality is a personality trait." The hardest one to dislodge because it feels generous. §23.8 is the antidote: hospitality requires capacity, standing, and information, and a three-week employee has none of the three. The move that lands is to walk back through the chapter's own asks — notice before they do, stop walking during the table touch, use $15 of standing authority — and ask after each one: could a server in week three do this? Six no's in a row makes the argument better than any assertion.

The hardest point to teach

That the "it was fine" guest is more expensive than the angry one. Students resist this hard, because everything in their experience says the complaint is the crisis. Expect pushback and let it run.

What works: make them price both. The angry guest generates a signal, a name, a table, and a recovery opportunity with a 13% break-even. The "fine" guest generates nothing — no complaint, no review, no survey response — and in a model requiring four visits a year, they take a full $220.80 with them and you never learn they left. Then point at the bottom-right box of Figure 23.1 and ask how a manager would find those guests. The honest answer is the 90-day gap report, and almost nobody runs it.

A second hard point, if you have time: the break-even reasoning itself. Students want to know "does recovery work?" and get frustrated when the chapter refuses to say. The frustration is the lesson. Sit in it.

Demonstration idea — "Price the Friday" (25–35 minutes, works in any class size)

Put only two things on the board: $116.70 (Chapter 14's cost of the second Friday in October) and eleven tables past the 22-minute standard.

Ask: what did that night actually cost? Take answers for five minutes. Most students will add up more hard money — a comped app, a wasted plate, some overtime. Almost none will price the guests.

Then walk them through it live, making them supply each number:

1. Eleven tables at 2.6 guests → 29 guests.
2. What is a guest worth? Build GLV on the board from $46 × 4 × 3 × 0.40 → **$220.80**.
3. If 10% never come back → 2.9 × $220.80 → **$640.32. Write "5.5×**" next to the $116.70.
4. Now ask what recovery would have cost. Let them build the $0 / $48 / $29 ladder → **$77.00**.
5. Finally: how well does the $77 have to work?* $77.00 ÷ $220.80 = 0.35 of one guest, out of 29 — a 1.2%* success rate.

The room goes quiet at step 5 and that is the whole class. Close by pointing out that steps 1–3 all required an assumption they cannot verify and step 5 required none.

Variation for a shorter session: give them only step 5 and ask what assumption it needed. (None.)

Where students get the arithmetic wrong

• Applying the 40% contribution ratio to a discounted check. They compute $36.80 × 0.40 = $14.72. Wrong: prime cost attaches to what was consumed ($27.60), not to what was charged, so the answer is $9.20. This single error is worth ten minutes.
• Forgetting that the review-offset formula has no $n$ in it. They will insist the number of reviews you have must matter. Have them derive it: $An + 1 + 5x = A(n+1+x)$, watch $An$ cancel.
• Confusing the two comp break-even figures. $12,400 ÷ $220.80 = 57 guests is the whole budget. $9,145 ÷ $220.80 = 42 guests is the overrun in Figure 23.4. Both appear in the chapter and students mix them up.
• Double-counting the re-fire food. In Exercise 23.18 the $8.52 of extra food is a cost of the error, not of the recovery decision. Both readings appear in the answer key; make them say which question each one answers.

Timing (a 3-hour block, or two 90-minute sessions)

If you have only 90 minutes: §23.2, the Friday demonstration, and §23.8. That is the argument.

Assessment guidance

• Exercise 23.27 (find the leak in the comp report) is the best single diagnostic in the chapter. It tests whether they read by reason code rather than by total, and whether they can resist the conclusion that a rising comp line is a generosity problem. Full credit requires naming Chapter 14, not Chapter 34.
• Exercise 23.21 (scale the ladder to a $28 check) separates students who memorized $15/$35/$60 from students who understood that the ladder holds a ratio to GLV constant.
• Exercise 23.32 (the Business Plan section) is the summative item. The rubric is in the answer key; the element most students omit is the falsification section, and it is the one worth the most.
• Exercise 23.31(b) (the abusive regular) is where you find out whether §23.8 landed. A student who answers it without doing any arithmetic has not understood the chapter.

Sensitivity notes

• §23.5's privacy material and Exercise 23.31(c) can raise real discomfort in students who have worked front-of-house and written notes they now recognize. Frame it as a policy failure rather than a personal one, exactly as the answer key does.
• Exercise 23.31(b) touches harassment. Keep it on the operator's decision and the arithmetic; refer the legal duties to Chapter 20 and note that obligations vary by jurisdiction.
• Case Study 1 involves a living, named individual and a real company. Keep discussion on the public record and on the business decision. There is no wrongdoing in this case and students should not be invited to speculate about any.
