documents: #Person1#: Excuse me, could you tell me which line I'm supposed to stand in to buy bubble wrap and to post a package?
  #Person2#: You can buy the bubble wrap here, but you'll have to stand in line over here to post your package.
  #Person1#: That's a really long line. How long do you think it'll take to get through all those people?
  #Person2#: It takes about 3 minutes per person, so it'll probably be about an hour's wait.
  #Person1#: Can I buy stamps here?
  #Person2#: Sure. How many would you like?
  #Person1#: I need 30 for my Christmas cards.
  #Person2#: Are you sending them abroad?
  #Person1#: Twenty of them are going abroad to China and America.
  #Person2#: Do you have any going anywhere in the EU? If you do, those are less expensive.
  #Person1#: No.
  #Person2#: Ok, here you go. That will be 18 pounds and seventy two pence.
  #Person1#: And the bubble wrap?
  #Person2#: That's another quid.
  #Person1#: Thanks a lot. You'Ve been very helpful.
