Well, they charge for sponges when you have surgery. Actually, my wife had surgery a few years ago. About the time the surgery was suppose to be over, the doctor came out of the waiting room and talked to me. Turns out they forgot to remove one of the sponges for her insides and wanted my permission to go back in and remove it! DUH! Imagine our surprise when the insurance was charged for 2 surgeries and all those sponges!
Nothing surprises me any more. Shop towels? Why not?
