The man says, “Yes, please. Can I see the menu (菜单)?”

“Certainly,” answers the waiter. The man wants a good meal and he wants a lot of nice dishes. After a moment, the waiter brings them to him. The man is having his meal happily. At this time, a boy comes in and sits down besides the man. He asks the waiter to give him an ice cream. The man says, “I will be back in 5 minutes.” Then he goes out.
