A man in the U.K. is trending because he does this every time he stays at a hotel.  Before he checks out, he strips the sheets off his bed and stacks them up, just to make the maid’s job a little easier. He posted a photo on Facebook of how he does it.  Some think it’s great and plan to start doing it.   But is this polite or totally unnecessary?
