J: Knocking three times, Turn-down service. May I come in? S: Come in, please. But I’m waiting for my friends to a nightclub. ( 你等一下再来 , 好吗 ?) J: Certainly, sir, but it is 10 o’clock, and I go off at 11 p.m. ( 如果您愿意 , 我 10 点半吧。) S: Well, I don’t know. They are a little late. J: Don’t worry. ( 您可以把“请勿打扰”的牌子挂出去 , 我看见后就不会来敲门的。) S: Then nobody will make up my room. J: Oh, I don’t think so, sir. If you don’t remove the sign when I leave ( 我会让值夜班的服务员来帮您整理的。) I wish you a good night. S: Thanks. Good night.
