 Clerk: Good morning, sir. May I help you?
 Mr. Lin: Yes, I am looking for a coat for myself.
 Clerk: What kind of coat, sir? Do you have anything in mind?
 Mr. Lin: I’d like one that is not too heavy but could keep warm from cold air.
 Clerk: How about these blue and green coats? They are both on sale.
 Mr. Lin: Well, they look a little old-fashioned,   39     ?
 Clerk: How about the pink one? It looks good on you. Here. Please try this on,   40     ?
 Mr. Lin: OK. (Five minutes later.)
 Mr. Lin: It is really nice. But…
 Clerk: You don’t like it,   41     ?
 Mr. Lin: Yes, it is nice. But it looks expensive.
 Clerk: No, not at all. It is only NT$500.
 Mr. Lin: Sounds good, I’ll take it.
