Five o'clock on a Friday.
The shift manager opens the kitchen display and sets tonight's capacity to twelve dishes per fifteen-minute window, two lower than a normal night because a chef is off.
The ordering site reads that number: a customer at six-ten is offered a delivery window of seven to seven-fifteen because the earlier windows are full, and the site tells her so instead of promising forty minutes.
Her address falls inside zone two, so the fee and the minimum order for that zone apply automatically.
She picks a half-and-half pizza, the modifiers the kitchen allowed, a meal deal that the ticket prints as one deal rather than three items, and a code from last week's flyer.
