Chapter 31 — Discussion Guide
1. Why does the restaurant industry need its own chart of accounts? Is that a real argument or professional territory-marking? What to listen for: the four structural peculiarities — perishable inventory that must be physically counted, an hourly workforce costed shift by shift, tax collected that is never yours, and a four-to-six-point margin. Strong answers name the ordering principle (group by who controls the cost and on what timescale) rather than listing accounts. Push the skeptics: ask what a generic alphabetical statement would have to add to be equally useful, and they will end up rebuilding USAR.
2. Work Exercise 31.2 together. Which food cost percentage would you put in front of a lender, and which would you put in front of your chef? What to listen for: the recognition that they are the same question answered for different purposes. The adjusted 32.06% is comparable to a cost card and is the operational number; the unadjusted 33.90% overstates kitchen performance failures by 1.84 points. Best answers notice that you show the lender the adjusted figure and the reconciliation, because the reconciliation is evidence you count.
3. The labor line has three true answers: \$500,000, \$570,461, and \$597,461. Which one is the plan's labor cost? What to listen for: resistance to picking one. All three are correct under stated assumptions, and the plan's defect was never stating which. Push hard on the follow-up: what does a lender do with a plan claiming 32.3% when the roster produces 36.8%? This is the chapter's central lesson and it should take real time.
4. Do the cancelling-errors demonstration, then answer: when would you ever use a fixed/variable split at a volume you already know? What to listen for: never — which is the point. A split exists to answer questions about other volumes, and Chapter 4's split fails everywhere except the one volume nobody needs it for. Strong students generalize: any model validated only at its calibration point is untested.
5. Your bookkeeper wants to move comps to marketing. Operating profit is identical. What do you say? What to listen for: the arithmetic first — net sales inflate by the comps, so every ratio above the line improves, and Bellwether's prime cost would read 61.36% instead of 63.00%. Then the operational point: comps are a revenue decision made during service and a marketing budget is a decision made in advance, and filing them together destroys your ability to see the first. Watch for students who accept it because "profit is the same" — ask which number they would use to change a schedule.
6. Chapter 9 says Q1 runs at 66.6% prime and weeks 14–52 must average 58.0%. What does a flat 60% target do to the flash report? What to listen for: it makes the report lie in both directions — green in a quarter that is bleeding, red in one that is fine. The best answers see that a target which is wrong in a known pattern is worse than no target, because it trains the operator to discount the report. Follow up: who is responsible for setting the ramp, and what happens when the actual ramp diverges from the planned one?
7. Case Study 2's restaurant had accurate books, filed on time, never failed an audit, and closed. What exactly did it lack? What to listen for: speed and aggregation, not accuracy. The statement arrived nineteen days late, the period was not comparable, prime cost was never subtotalled, and comps inflated net sales. Best answers land on the owner's line — "I had numbers. I didn't have information" — and can state the cost comparison: \$6,000–9,000 a year for the bookkeeping it had, \$94,400 a year for the reporting it didn't. Close by asking what two hours a week is worth, and who in Bellwether's fully committed salaried week is going to spend it.
