A: Good afternoon Sir, may I please see your passport and reservation?
B: Here you go.
A: I'm sorry sir, this flight has been cancelled due to some mechanical problems.
B: Cancelled! So what am I supposed to do now?
A: We apologize for any inconveniences that may be caused by this. If your flight is urgent, I can put you on a waiting list for another flight this evening, but it's on a first come first served basis, so there is no guarantee that you will be able to take that flight.
B: What's my other option?
B: That's fine. I'll do that then.
A: Thank you for your understanding sir. I will book your flight now.
