听力原文：W: Can I help you, sir？

M: Um, yes. I bought this radio cassette player here a couple of weeks ago. Here's the receipt.

W: Ah ha. That's fine. What seems to be the problem？

M: Well, it's been nothing but trouble since I bought it.

W: OK. Just let me take a note of this. Er, radio cassette player.

M: The first thing is one of the speakers doesn't work properly. The sound is completely distorted with the radio or a tape.

W: Which one is it？

M: The right-hand one. Another problem is the left cassette player. It chews up tapes. It's completely ruined two of my favorite cassettes.

W: Oh, dear. The speaker and the cassette player.

M: One of the cassettes was brand new. Oh, and the rewind switch doesn't work. Actually it never did.

W: OK. So there is the right-hand speaker ... the cassette player and ... urn, the rewind switch. Is that it'？

M: No, I'm afraid not. The aerial doesn't work properly. It's stuck.

W: Hmm, 1 see what you mean. The handle is broken too.

M: Yes, I'd forgotten about that. It's not very good, is it？

W: Er, no. But it's under guarantee and we can repair it. Just give me your name and phone number. We'll give you a ring when it's ready.

Where are the two people, most probably？

A．At an electric appliances store.

B．At a repair shop.

C．At a restaurant.

D．At a garage.
