Short answer

19. In one sentence, why does the fixed-cost-absorption argument for delivery ("the rent is already paid") fail during a binding hour?

20. Bellwether's modeled $65.00 order carries $19.32 of plate cost, $2.24 of packaging, and $1.30 of packing labor. Compute its contribution at a 20% commission and state it as a percentage of the order.

21. Name four ways to test incrementality without running an experiment, and one way that requires one.

22. Explain why a compostable container can be the more expensive and the less sustainable choice in a given market.

23. A guest's allergy note arrives on an off-premise ticket. What replaces the conversation a server would have had at the table, and what does that mean operationally?

24. Bellwether keeps its $31,200 takeout line. Name three specifications the chapter changed underneath that number, and state the annual contribution difference between first-party pickup and a 25% marketplace on the same sales.


Answer key **1. b.** Off-premise is any food prepared in your kitchen and consumed elsewhere — takeout, curbside, drive-through, delivery, and catering. **2. c.** The beverage. Dine-in contribution was $61.76 against $25.89 for a 25% marketplace order; the $25.76 of beverage on the dine-in check is a larger single factor than the $16.25 of commission. **3. b.** Promotional funding, sponsored-listing spend, and error refunds charged back — plus any per-order or hardware fees. **4. b.** 15–30%, varying by service tier, market, platform, and contract. Treat any specific figure as one restaurant's deal. **5. b.** **6. c.** The cheaper channel tolerates more cannibalization before it stops adding contribution, which is a tolerance for being wrong about the one variable you cannot measure. **7. c.** 29 items produced against a 28-item sustainable rate = 104%. **8. d.** 46 covers × $33.23 = $1,528.58 of contribution in the hour, ÷ 29 hearth items = $52.71. **9. a.** About four minutes. Steam condenses in a closed container and there is no packaging solution. **10. c.** A braise was cooked in liquid and is essentially unharmed to 45 minutes. **11. c.** ($29.00 + $1.20) ÷ 0.75 = $40.27, a 38.9% uplift — which is the practical answer to whether this dish belongs on a marketplace. **12. c.** $19.50 × 5 × 5 = $487.50, which exceeds the $357.60 a week the whole 12-order channel produces before packing labor. **13. b.** Around 5% of sales — roughly 30 orders a week at a $50 ticket — and even there the return is thin. **14. b.** During the 2020 shutdowns; New York City, San Francisco, and Seattle were among them, with caps commonly around 15% for delivery. Some were later made permanent, and at least one drew litigation. **15. c.** Adding or raising guest-side fees — the predictable result of regulating one side of a two-sided market. **16. b.** A verification step by a second person. It takes twenty seconds and removes most of the defect rate; the refund line in Figure 28.4 was 3.6% of menu sales, larger than packaging and packing labor combined. **17. b.** It cuts the food's age at the door — the twenty-minute clock starts when the item leaves the pass, not when the driver arrives. **18. c.** $185 of promotions plus $142 of ads = $327 on $4,732 of menu sales = 6.9 points of take rate, neither of which required an authorization step. **19.** Because the resource the order consumes was not idle — it was already producing higher-margin work, so the order reallocates scarce capacity rather than absorbing spare capacity, and both transactions still record as sales. **20.** Commission $13.00 → remittance $52.00; own costs $19.32 + $2.24 + $1.30 = $22.86; **contribution $29.14**, or **44.8%** of the $65.00 order. **21.** Without an experiment: the baseline test (dine-in covers before and after), the constraint test (is a resource binding during the channel's hours), the geography test (delivery addresses inside or outside the walk-in trade area), the guest-overlap test (matching phones and emails against the reservation and loyalty lists), and the daypart-shape test (when orders arrive relative to dine-in peak). Requiring an experiment: the blackout — turning the channel off on Friday and Saturday for two weeks and measuring dine-in covers. **22.** Compostable containers cost more per unit and are only compostable where commercial composting exists and accepts them. In a market with no organics collection, the container is landfilled — you paid a premium for an identical environmental outcome. Verify what your municipality actually does before you buy the more expensive box. **23.** The label replaces the conversation. Operationally that means allergens must be named on the container where present, an allergen note on the ticket becomes a stop-and-check step rather than a preference, and the packer is the last line of defense because there is no server standing at the table. **24.** Any three of: first-party pickup only (no marketplace, no delivery); the channel closed 6:00– 8:45 p.m. Friday and Saturday to protect the hearth; a nine-item off-premise menu with the pasta off it and the Hearth Chicken carrying a documented compromise; price parity; labor absorbed rather than added, with a 30-orders-a-week trigger to revisit. The contribution difference on the same $31,200 of sales is **$17,984 first-party versus $11,276 marketplace = $6,708 a year**, or 21.5% of the whole line.
