C: Hello. What can I do for you?
A: I am wondering how to get to the Agricultural Exhibition Center Station.
C: Well, the shortest way to there is by Line 12.
A: How much is it?
C: 50 cents. Haven't you get any token?
A: Not yet. How can I get it? I am a foreigner here.
C: Use the token machine over there. I will show you how to use it. Do you have 50 cents?
A: Oh, I don't have any change.
C: Let's use the change machine. What you need to do is putting the bill face up.
A: I got it.
C: That's it!
A: Shall I get a monthly ticket here?
C: Of Course. The monthly ticket is much cheaper.
A: Then, I'd like to have one. Thanks a lot!
C: My pleasure!
