I want to be a waiter and a summer job in a restaurant, but I haven't done it and I don't know anything. Can someone teach me something related, such as how to deal with it?

Actually, it's still very simple. They will tell you as long as you study hard. If not, ask humbly. Ask if you don't understand. Don't be shy. Mainly to entertain some guests who come to dinner and help them order. If the guest has any orders, please try to satisfy her and serve the guests well. After all, the service industry must have a better attitude.
