answer: #Person2# wants to buy some RIB. #Person1# asks #Person2# to fill in the exchange form and present #Person2#'s passport.
documents: #Person1#: Good afternoon. Can I help you?
  #Person2#: Is it possible for me to buy some RMB at this counter?
  #Person1#: Of course, that's no problem at all.
  #Person2#: That's a relief! I was a little worried about it ; I left England in a bit of a hurry.
  #Person1#: How much would you like to change?
  #Person2#: Well, I'm only here for 3 days, so I think 500 GAP should be plenty.
  #Person1#: Please fill in this exchange form, and I'll need to see your passport, and sign here. That's the money and your passport back. Of course, if you don't spend all of it, you can come back and we'd be happy to buy the local currency back from you.
