When the guest arrives at the door of the ordering hall, he will greet him with a smile, and then tell him where the cold dishes, hot dishes, pots and seafood are as he walks in. When the guests arrive at the specific food area, they will introduce the characteristics, tastes and ages of various dishes to the guests, and ask how many they have, reminding them that the number of dishes is similar. Then ask when to pick up the food and let the guests wait in the private room. Note: smile, don't order for other guests, don't recommend the same dish twice or many times, and always stand behind the guests.
