documents: #Person1#: Hello Mr. Waterstone, what can I do for you today?
  #Person2#: Hello, Becky. Well, you see, I have this thing here, called a Fixed Deposit Certificate, and I've just noticed the date on it.
  #Person1#: Oh, I see. You have two choices here you can either redeem or renew.
  #Person2#: I think I'll redeem, if that's not a problem.
  #Person1#: No problem at all, Mr. Waterstone. Any preference as to how you want the money?
  #Person2#: Anything you like, but not too many large notes. It's useful to have smaller notes.
  #Person1#: Here we go, Mr. Waterstone. Here's your money and your interest note.
  #Person2#: Yes, yes. Everything's fine. Thank you very much, Becky.
