A: how can I help you? B: I seem to have lost my train ticket. A; what's your destination? B: I'm supposed to be going to ShangHai. A: ok. When is your train supposed to leave? B: it's supposed to leave in 30 minutes. A: OH, dear. What's your last name, please? B; S M I T H. A; and your passport number? B: Z3264356. A; let me see…it doesn't look like we have any information about your ticket here. B; is there anything you can do for me? If I don't make it to ShangHai in time, my wife is going go kill me. A; oh dear. I'm really sorry , sir. But you don't have any proof of purchase. You'll simply have to purchase another ticket. B: how much is that going to cost me? A; it depends on how you want to travel. If you want a soft sleeper, it will cost 610 RMB; if you want a hard seat, it will only cost 100RMB. B; I can't possibly travel on a hard seat for 10 hour! A: looks like you might like the soft sleeper then. B: yes, fine. Let me see how much money I have I my wallet. A: …sir? B: where's my wallet? Someone has stolen my wallet! A; perhaps it's in your other pocket. B: you're right. It is. Let me have a look. I have 419.6RMB. is that enough? A: you're just 4 mao short for the hard sleeper, but I'll let it go. Anything for love! B; thanks, ma'am. You're a lifesaver!
