A man walks into a bank and says he’s is going overseas for two weeks and needs to borrow $5,000. For collateral, he offers his new Rolls Royce. The bank is satisfied and parks it in their secured underground garage.

Two weeks later, the man returns to the bank, repays the $5,000 and interest of $15.41. The loan officer says inquiringly, “Sir, we were delighted to have your business but, in checking your credit, we learned you have a millionaire” Why ever did you need to borrow $5,000?” The man replies, “Where else can I park my car safely for two weeks for $15.41?”
