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 you name and address ?   David Hall , 83 , Bridge Street .   That's right . D.N.Hall . 83.Bridge Street . Three pound and fifty pence please .   Here you are .
