L:You want to fly first class. Is that correct, Mr. Smith? S:That's right. L:Well, I booked three first class tickets for you and they're already reserved. Your seat numbers are 9A, 9B and 9C. S:Those are in the non-smoking section, aren't they? L:Yes, they are. I've charged the tickets to your credit card. They are 600 dollars each, so it's 1800 for all three. S:Fine, thank you very much.
L:Have a nice flight. S:Thanks.
