Marcel -- the sin of being annoying. Is that a sin? Kinda. It's not acceptable to say you don't care what other people think of you. Man is a social animal and it's really hard to be successful in life if you make no effort to understand your effect on your fellow man. Betty -- the sin of overreaction. Let's face it -- if anyone else had asked her to "hold" in the same tone of voice, she would have been fine with it.
