I need to reserve a flight now.
May I have your name, please?
Ugh I don't see why you need that but it's Susan.
Flight ID?
680.
The flight is available. Should I reserve it for you?
Hang on I guess the flight is 289.  You got me confused with all your questions and I typed the wrong number.

Yes.
I'm sorry, but your reservation request was unsuccessful.
Great.  I knew this was a waste of time.  Thanks for nothing.
Thank you and goodbye.
