Grace: excuse me, could you tell me which line I’m supposed to stand in to buy bubble wrap and to post a package?
Alexander: you can buy the bubble wrap here, but you’ll have to stand in line over here to post your paskage.
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 Chrismas cards.
A: are you sending them abroad?
G: twenty of them are going abroad to China to America.
A: do you have any going anywhere in the EU? If you do, those are less expensive.
G: no.
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’ve been very helpful.
