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