How to save money?

A businessman walks into a bank in New York City 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 forsuch a loan. So the businessman hands over the keys to a Rolls Royce parked onthe street in front of the bank. Everything checks out, and the bank agrees toaccept the car as collateral for the loan. An employee drives the Rolls intothe bank's underground garage and parks it there. Two weeks later, thebusinessman 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, andthis transaction has worked out very nicely, but we are a little puzzled. Whileyou 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?" The businessmanreplied, Where else in New York can I park my car for two weeks for 15 bucks?"
