How do you avoid burning offers too early?

An offer waits for a day that is genuinely quiet, with an end date and a dish the floor can serve without breaking the pass. Announcing it on Friday fails if Saturday is already full: you only teach the guest to wait for the discount. The floor marks two days in the month that usually run short, and the kitchen says which dish can take an extra without delaying the rest. A two-for-one runs every week and, when a Tuesday in January actually needs filling, nobody believes it. The calendar parks offers on specific days, with a start and an end, and the rest of the month shows the dish at menu price.
