You can't blame the guests. You are a restaurant or a place to eat, and guests are coming. They come to dinner for various reasons. People who go to work come to dinner on time in order not to be late for work, and those who rest in the morning come to dinner later if they want to have a rest. Sometimes I'm too busy at work to come to dinner on time. In order to hurry, I may come to dinner early, and suddenly I will come to dinner at any time when I meet my friends. I decided to eat temporarily when there were guests at home. Due to the reception of guests from all over the world, guests will come to dinner in different ways for various reasons. Working in a restaurant is hard!
