MR Singh walks into a bank in Central London and asks for the loan officer. He says he is going to Europe on business for two weeks and needs to borrow £5,000.

The bank officer says the bank will need some kind of security for such a loan, so the Mr Singh hands over the keys to a new Rolls Royce parked on the street in front of the bank. Everything checks out, and the bank agrees to accept the car as collateral for the loan. An employee drives the Rolls into the bank's underground garage and parks it there.

Two weeks later, the man returns, repays the £5, 000 and the interest, which comes to £15. 41. The loan officer says, "We are very happy to have had your business, and this transaction has worked ut very nicely, but we are a little puzzled. While you were away, we checked you out and found that you are a multimillionaire. What puzzles us is why would you bother to borrow£5, 000?"

Mr Singh replied, "Where else in London can I park my car for two weeks for £15 ?"
