[speaker001:] Can I still catch T107 for Xiamen?
[speaker002:] Sorry, sir. The train has already left.
[speaker001:] That's too bad. Can I take another train?
[speaker002:] Yes. Your ticket is valid for three days.
[speaker001:] That's great! I will take the next train.
[speaker002:] You have to have your ticket checked.
[speaker001:] Shall I pay extra charge?
[speaker002:] No extra charge at all. But your berth will be invalid.
