Each choice explained
Warming the food — Best fit

Canceling the whole order — Does not fit
No cancellation is requested. Cancelling the entire order expands a request concerning food already served.
Making the entire meal free automatically — Does not fit
No fee waiver is demanded. Discomfort does not automatically establish a request for financial compensation.
Confirming a change to a different dish — Does not fit
The guest asks to warm this dish, not to replace it with another menu item. A substitution changes the target.
