Mr Hall : I left a suitcase on the train to London the other day.
Attendant : Can you describe it, sir?
Mr Hall : 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.
Attendant : Is this case yours?
Mr Hall : No, that's not mine.
Attendant : What about this one? This one's got a label.
Mr Hall : Let me see it.
Attendant : What's your name and address?
Mr Hall : David Hall, 83, Bridge Street.
Attendant : That's right. D.N. Hall, 83, Bridge Street.
Attendant : Three pounds fifty pence, please.
Mr Hall : Here you are.
Attendant : Thank you.
Mr Hall : Hey!
Attendant : What's the matter?
Mr Hall : This case doesn't belong to me! You've given me the wrong case!
