Hotel resilience: what should guests do if they complain after eating?

Ask him what's wrong with the food. When you see that the food is finished, talk about it. If you have any questions, ask them early. You can change what you have already eaten. Almost enough. Hotel regulations are not allowed to be changed. That's it. If he wants to have face, he won't mention it again. If you still talk nonsense, do you need to give him face? Tell him you have a problem after dinner. This doesn't exist.
