Collection times are production planning here. If twenty orders land for seven o'clock, the system has to stagger them, or half the platters are ready twenty minutes too early and it shows.
Traceability on the fish belongs in the system. Delivery, batch, date: on a product eaten raw that isn't paperwork, it's the basis of any inspection.
Bookings and orders share the same evening. Run separately, at eight o'clock the room is full and the kitchen is simultaneously buried in collections, and nobody saw it coming.
