Order throttling
Order throttling is a cap on how many orders, or how much order value, a system will accept in a given time window, usually fifteen or twenty minutes. Beyond the cap the next customer is offered a later slot instead of being added to a queue the kitchen has no chance of clearing. It is the difference between a busy Friday and a bad Friday, and it costs one customer ten minutes rather than fifty customers cold food.
In practice
Throttling limits the number of orders, or the total value of orders, that a system will accept for any given fifteen or twenty-minute window. Beyond the cap, the next customer is offered a later slot rather than being quietly added to a queue that is already too long.
It is the difference between a busy Friday and a bad Friday. Without it, the website keeps taking orders at the advertised wait time while the kitchen falls further behind, and every one of those customers gets cold food and a reason not to come back. With it, somebody waits ten minutes longer at the point of ordering, which is the one moment they do not mind.
Throttling only works if the quoted time shown on the website is the same number the kitchen is working to. If the two live in separate systems, the promise and the reality drift apart by about an hour into service.
Also called: order capping, slot limits.
