I'm considering not giving vegetable to a customer that never eats them.
Okay, but did he ask to have no vegetables in his order or at least tell him you're going to remove the vegetables?
No, but I hate him, the vegetables always end up getting thrown out.
You should always give the customer what they order. If they choose not to eat it that is their problem.
I don't really care. I will do what I want. I'm out to spite that guy.
I agree that it can be wasteful for him to not eat what he orders, but unless you have told him that you will be removing the vegetables, then I do not think you're in the right to remove it without saying it to him. You're changing the item that he orders and I do no think that is legal. If you ordered something and received something that's incomplete, you won't want that as well, right?
