Situation
The team has committed to an offer, a volume, and a staffing plan. Each costs money or gives some up. The discount cuts what every promotional cup earns. The acting lead is paid extra. Backup coffee costs more. Refunds and remakes come out of the day's result.
The owner has said the cash reserve is not available for Friday. A busy day that ends with less money than a normal one, or that dips into the reserve, is a failure however many customers came. Draw the lines now: price, extra spending, minimum result, and what would make the team stop.
Work through one cup first. What the café charges, what the discount removes, what the coffee and cup cost. What is left is the contribution per cup. Multiply by the task 2 volumes, subtract the task 3 labor, and you have a rough Friday result under each scenario.
Then set the guardrails tasks 5, 6, and 7 must respect and task 8 will check: a ceiling on extra spending, an untouched reserve, a break-even volume, and a stop rule. Write them so a teammate could apply them without you.
What is at stake: More sales can still produce a worse result when discounts and rush-related costs rise faster than contribution.
What price, spending ceiling, cash reserve, and minimum result must guide Friday decisions?
