I don't pay until the end because what if it gets cut short or something? I have never forgotten to pay - I don't want to pay ahead of time until I receive the time.

The first one did try getting up and coming at me at the door - which I though was pointless. I know where the door is, I am willing to leave, and it is a small room with only about 4 feet from the awful couch that clients must endure to the door. It is not like I was going to get lost.
I made her stop doing that after the second or third time. I thought she was nuts. She said she thought it was polite. I would rather her stay back.
