"Air Level" is a word in ENGLISH

A woman walks into a bank in New York City and asks for the loan officer. She says she is going to Europe on business for two weeks and needs to borrow $5000. The bank officer says the bank will need some kind of security for such a loan, so the woman 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 woman returns, repays the $5000. and the interest which is $15.41. The loan officer says, "We are very happy to have had your business, and this transaction has worked out 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 $5000 ?" The woman replied, "Where else in New York, can I park my car for 2 weeks for $15.00?"
