When I saw Bernadette Peters in Gypsy this old woman behind me started singing with "You'll Never Get Away From Me".
I saw Les Mis in Boston last weekend and these people who were sitting in the row in front of me, if something funny happened they would repeat it and be like "haha, master off the ass, did you hear that?" soo annoying.
I saw Romeo and Juliet at the Met and there were young people behind me who were talking and talking, I wanted to smack them, it's so rude to the people around you who are actually listening. But they left during intermission :)
and I also hate people who stand up and leave before the actors take their bow, the Met was half empty when the actors came out.
