Once it was my time to have one done. I lay on the stainless table in the paper gown till I was froze. I got tired of waiting and freezing and began to gripe to my wife who was waiting with me. I complained that even though the Dr.'s time was valuable my time was worth something to me and so forth. I happened to look toward the door and could see the Dr.'s shoes under the door. He was standing there listening to me fuss. A piece of advise,never allow yourself to be heard complaining by the Dr. who is going to put that scope.... Well you get the picture.
