Hello. I sure hope someone can help me this time.
Hello, how can I help?
I need to reserve a flight and you better hurry up.
May I have your name, please?
My name is Mark and I need flight 107.  Oh, I mean flight 825. You people are always changing these and I'm quite sick of it.
Sorry, but the flight with id '825' is not available any more.
Oh, imagine that! You people can't get anything right.
Is there anything else that I can do for you?
No, never mind, I guess. Goodbye.
Sorry for the inconvenience, goodbye.
