A、In a supermarket. B、At a shop. C、In a grocery. D、At a repair shop. B女士说自己一年以前在店里买的MP3播放器。由此就可判断对话发生在商店里。

M: Hello, Madam. What can I do for you?
W: Hi. Uh... I bought this MP3 player here one year ago. But it doesn’t work now.
M: Oh, dear. I am sorry to hear that.
W: I want to have it fixed. I am sure you can deal with it, right?
M: Absolutely. Will you please show me your sales slip?
W: Yeah, here it is.
M: I’m sorry, Madam. We can fix it for you, but I’m afraid that you have to pay for that.
W: Why? You promised that you would fix it for free if it has any problems.
M: Yes, we did. But that was valid within one year. You see, yours has run out.
W. Well, it...uh...ran out a week ago, but I didn’t drop it off a building or anything. What difference can a week make?
M: I’m sorry. We only have a one-year guarantee. So we can’t...
W: Can’t you make any exception? That is only a week.
M: Sorry, Madam. If we make it for you, we’ll have to make it for everybody.
W: Actually it didn’t work a week ago, but at that time I was too busy to bring it here. So strictly speaking the time when it got bad was really within the one-year guarantee.
M: Well, Madam. You should have brought it in earlier. There is nothing I can do for you.
W: So you surely can’t give me an exception?
M: Sorry, Madam. The rules are the rules.
W: OK. You just fix it. I’ll pay for that.
