  #Person1#: Alright. Do you have your receipt?
  #Person2#: Yes. Here it is. I bought them last week.
  #Person1#: And why are you returning them?
  #Person2#: I bought them to go with a blouse of mine. But they don't really match.
  #Person1#: I see. Oh, wait. Ma'am, I'm sorry. These slacks were on sale.
  #Person2#: Yes, they were thirty percent off.
  #Person1#: I'm sorry, but we don't allow returns on sale items.
  #Person2#: I know many stores have that policy. But I have returned sale items here before.
  #Person1#: I'm sorry, but we usually don't do it. It is our policy.
  #Person2#: I just bought these slacks a week ago. And I am a regular customer here. Can you make an exception this time?
  #Person1#: Well. Let me talk to the manager for a moment. Madam, the manager says can do it this time.

  #Person1#: Please show me your receipt again.
  #Person2#: Here it is.
  #Person1#: I will have to give you store credit, Madam. If you can find something else you like in the store, you can use the credit.
  #Person2#: Store credit is okay with me. I'm sure I will find something I like. I shop here a lot.
  #Person1#: We appreciate your business, Madam.
