documents: #Person1#: Good day. How can we assist you?
  #Person2#: I need to get a Letter of Credit. Is this the right window?
  #Person1#: It certainly is. Do you have your contract and Import License?
  #Person2#: Yes, right here in my brief case. Just a moment, please.
  #Person1#: Thanks. What you need to do now is deposit 100 % of the guaranteed funds of your contract into your account with us.
  #Person2#: That's done. There is more than enough to cover the contract amount in our account.
  #Person1#: That's great. We will have to charge you 250 RMB for that service, though. Could you please fill in this? Thanks.
