Excuse me, but could you tell me when the plane for Berlin leaves?
In 40 minutes, at eleven o'clock. The plane for Berlin leaves every two hours.
How much is a second class ticket, please?
We have only first class tickets left. It is $ 350 one way.
OK. I'd like one for the next flight.
I'm sorry, but I don't sell tickets. You can get one from the machine over there.
All right. By the way, what's the gate number?
Four. Down the hall and to the left.
