    A: How many pieces of luggage do you want to check, sir?
    B: I have two.
    A: Fine. Do you have any hand luggage?
    B: Yes. I have these two small shoulder bags.
    A: That’s fine. But your luggage is three kilos overweight, so I’ll have to charge you.
    B: Just a minute, please. I’ll carry my dictionary in my hand and then it won’t be overweight.
    A: That’s fine, sir. Your flight leaves from Gate 13A at 7:15 exactly.

    A: It’s over there, to your left.
