answer: #Person1# is sending a package and #Person2# instructs #Person1# how to buy bubble wrap and post a package. #Person1# also buys some stamps for Christmas cards.
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 paskage. 
  #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 Chrismas 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.
