I want a ticket to New York, one way please.
That'll be $285. How would you like to pay?
Credit card. I don't like to pay in cash because it's quite inconvenient.
OK, I see.
Oh, by the way, my doctor advised me not to eat any meat. Last time I had a special salad plate. I'd like to have it again this time.
I'm sorry, I'm not able to do that. Otherwise, we would need 24-hours notice for special meals. Here is your ticket.
