M: I bought these trousers here on Wednesday. When I tried them on at home, I found them too small for me. Can I return them and get my money back? ,F: I'm sorry. You can't because you bought them at a sale price. However, you can exchange them for a bigger size. ,M: I have already looked around here, but I can't find the proper size for me. I have to wear them at my co-worker's house warming party this Saturday.
(A) F: No problem. We will find a smaller size for you before you go to party on Wednesday. (B) F: If you are going to a party on Saturday, we can find a proper size for you before that date. (C) F: Of course. If you are going to a party on Friday, you can return them and get your money back. (D) F: I’m sorry, I don’t understand. Could you say it again?
