Excuse me, could you tell me which line I'm supposed to stand in to buy bubble wrap and to post a package?
You can buy the bubble wrap here, but you'll have to stand in line over here to post your package.
That's a really long line. How long do you think it'll take to get through all those people?
It takes about 3 minutes per person, so it'll probably be about an hour's wait.
Can I buy stamps here?
Sure. How many would you like?
I need 30 for my Christmas cards.
Are you sending them abroad?
Twenty of them are going abroad to China and America.
Do you have any going anywhere in the EU? If you do, those are less expensive.
No.
Ok, here you go. That will be 18 pounds and seventy two pence.
And the bubble wrap?
That's another quid.
