听力原文：Allen: Excuse me. Could you help me? I'd like to exchange this sweater. Clerk: What is the problem with it? Allen: It was a birthday present, but I don't really like it. I think I want something plainer. Clerk: I see... Well, Why don't you look around. Allen: This one looks nice. I want to try it on. I kind of like the black one. Clerk: I think the red one is longer and a little looser so it will be more comfortable. Allen: True, and it feels softer. Clerk: And that color looks better on you. Actually, it is better quality and it is the same price as the sweater you are exchanging. Allen: You have talked me into it! I will take this one instead. Clerk: No problem, I will switch them for you. Where did the customer get the sweater?
