Q: M: No, I'm not. I'm interested in some hats. W: All our hats are in this section. What do you think of this one here? It's made of cotton. M: Hmm,it looks nice and is suitable for autumn, but I'd like to have something warm for winter. W: Maybe you would like a heavy wool hat. How about this one? M: I think that's what I want. How much is it? W: It's seventy dollars plus tax. M: It's a little expensive. Do you think it's possible to get a discount? W: Hmm, since you like it so much, how about a 10 percent discount. That's the best I can offer. M: That's good. Could you wrap it up for me? W: Sure. Is there anything else I can get for you? M: I also want to have a red wool sweater. But there are only black and green ones. What was said before this conversation?
