UM HELLO?
Hello, how can I help?
Check 472. I need a flight, guy.
May I have your name, please?
It's Ben. What else?
Sorry, but the flight with id '472' is not available any more.
FINE. 3 plus 1 plus 1 equals 5, and you have 5 seconds to figure out if flight 311 can be booked. Got it?
The flight is available. Should I reserve it for you?
Do it.
I'm sorry, but your reservation request was unsuccessful.
How?
Sorry, the system will not accept the reservation.
OK THEN BYE
Thank you and goodbye.
