I think cell phone users who allow their phones to ring during performances need to be kicked around. Answering the phone should be punishable by death.
I also can't stand the women who bathe themselves in overpowering cheap perfume. Remebers ladies, the point of the scent is that it so subtle taht it should draw someone closer to you in order to smell it...not repel them.
At a performance of Fosse a while back, I got into an intermission fight with a family who felt it was ok to talk through most of act 1 because, as they explained when I confronted them, "It was just music, there wasn't nobody talkin on the stage so what you need to listen to?"
The argument with them got so out of hand because they became defiant and threatened to talk as much as they wanted through act 2 that the house manager had to assign an usher to stand in the aisle near them and shush them everytime they opened their mouths.
