I have had my moments as well
I recall one incident in Atlanta 25-30 years ago when I was on a room phone trying to get my car out of the hotel garage to drive to a meeting. There were several people in the room with me and I totally lost it. If I had been in the lobby it would have been almost as bad as the crazy guy.
Very embarrassing in retrospect and my blood has long since cooled to the point that it woud not happen now. A little muffled cursing is about all I can muster these days.
