Re the staff not recognizing you without your uniform: when I worked in a hospital, I spent a lot of time with residents (specialists in training) who wore surgical scrubs. One day after getting off work, as I was boarding the streetcar, a strange man spoke to me in a very familiar way. I was all prepared to be insulted when I realized it was one of my co-workers in street dress. I said, "Oh Danny! I didn't recognize you with your clothes on!" I suppose that's an old joke.
