this is the problem of the hotel. Because customers won't have much patience to wait for you to serve when they go to dinner, they have to serve food in five minutes at most, but they haven't served for more than ten minutes. There are also objective reasons for restaurants, because there are too many customers, so serving food is a little slow, which is also common sense. But the mistake is that you didn't do a good job of appeasing customers. For example, after customers order food, the restaurant should serve customers with melon seeds or fruit plates first. The waiter should politely say, "There are many guests today, so you may have to wait a few minutes longer than usual, so you should eat melon seeds and fruits first, and we will serve them as soon as possible." In the face of such courteous and thoughtful service, I believe that customers' emotions will be balanced.
