NCE1-97 A small blue case

Does Mr. Hall get his case back?
I left a suitcase on the train to London the other day.
Can you describe it, sir?
It's a small blue case and it's got a zip.
There's a label on the handle with my name and address on it.
Is this case yours?
No, that's not mine.
What about this one?
This one's got a label.
Let me see it.
What's your name and address?
David Hall, 83, Bridge Street.
Three pounds fifty pence, please.
Here you are.
Thanks you.
Hey!
What's the matter?
This case doesn't belong to me!
You've given me the wrong case!
