The pain doctor I was seeing back in the 90s was notorious for running late, real late. I would call before starting out and be told he was running on time and have a three or four hour wait........standing room only with people waiting outside. I finally warned the office manager that the next time I had an appointment, I would call first and then bring a sleeping bag and pillow with me just in case I arrived to a major wait. She laughed. While I was soft spoken, I wasn't kidding. The next appt. rolled around, I arrived and the patients who were lucky enough to have chairs said they had been waiting for hours. I went to the car and got my sleeping bag and pillow. I got the next open room which caused a near riot but that was their problem.
