dialogue: #Person1#: Yes. Can I help you?
  #Person2#: Yes. You see, I've bought this personal stereo at your shop 3 days ago. And I'm afraid it hasn't really matched up to what I was told about.
  #Person1#: I see, what exactly is the matter?
  #Person2#: Well, first of all, there is this large scratch across the front of it.
  #Person1#: But you should have noticed that when you bought it.
  #Person2#: But it was in the box and all sealed up.
  #Person1#: Well. I'm sorry, but it really is your responsibility to check the goods when you buy them. How are we to know that it wasn't you who made the scratch?
  #Person2#: But that's ridiculous. But anyway, it's not the most important thing. I really am not happy about this other thing.
  #Person1#: And what is that?
  #Person2#: Look. It says here that the noise from it should be undetectable by other people.
  #Person1#: Yes, that's right.
  #Person2#: But people can hear it, and it's really embarrassing on the bus and underground.
  #Person1#: Well, I'm sorry, but it must be the way you are wearing the headphones.
  #Person2#: Look. I know how to put earphones in my ears. Thank you very much. But what I want to know is, what you are going to do about it at all?
  #Person1#: Well, I suppose we could exchange it for another model, if you really aren't happy with it.
  #Person2#: No, I certainly am not.
  #Person1#: Well, if I could just have the receipt.
  #Person2#: Oh yes. Well, there is a slight problem about the receipt.
