Food comping should only be used in extreme cases. By comping food, you train your customers to expect it. Then when you don’t, they’re dissapointed for not getting something they wouldn’t have gotten at another restaurant anyways.

A customer that simply orders something they end up not liking, not because it was bad, but because it doesn’t suit their taste, is never someone whose meal should be comped in my opinion. Along with other complaints from customers who eat most or all their meal, or do not have enough of an appetite to let you make them something else, you should be offering these people some sort of bounce back offer instead of a comp.

Your first approach should always be to try and replace the food with something they do like. Even if you have to make a dish twice, as long as you collect the money for it…
