G: Excuse me, could you tell me which line I'm supposed to stand in to buy bubble wrap and to post a package?
A: You can buy the bubble wrap here, but you'll have to stand in line over there to post your package.
G: That's a really long line. How long do you think it'll take to get through all those people?
A: It takes about 3 minutes per person, so it'll probably be about an hour's wait.
G: Can I buy stamps here?
A: Sure. How many would you like?
G: I need 30 for my Christmas cards.
A: Are you sending them abroad?
G: Twenty of them are going abroad to China and America.
A: Do you have any going anywhere in the EU? If you do, those are less expensive.
A: Ok, here you go. That will be 18 pounds and seventy two pence.
G: And the bubble wrap?
A: That's another quid.
G: Thanks a lot. You're been very helpful.
