Paul bought a camera yesterday that doesn't work. He returns it to the store. Tim, the salesman, helps him make an exchange.

Paul: Hi, I bought this camera here yesterday, and it's not working.

Tim: Did you charge the battery and put it in correctly?

Paul: Yes. I followed the directions to the letter.

Tim: Do you mind if I take a crack at it?

Paul: Be my guest.

Tim: I usually have the magic touch ... Hmmm, you're right. It doesn't work. Would you like a replacement?

Paul: No, this is the second one I've had to return. I think I'll steer clear of this model.

Tim: I hear what you're saying. It's frustrating when you get one bad unit, let alone two!

Paul: Yeah, it's a bummer! I'd like my money back.

Tim: If you give me your receipt, I'll issue a credit to your credit card. But you might also try a different model or brand.

Paul: Maybe I will try a different camera.

Tim: We've got an excellent Canon camera that's the same price as this one. It would be an even exchange.

Paul: Okay, I'll take it. I hope this one works out.

Tim: If you 're not happy with it, don't hesitate to bring it back.
