The phone people.
Why do they pay all that money, just to sit in a dark room surfing Facebook? They could just go into their bedrooms, turn off the lights, and the same thing would be achieved. Why do they bother venturing out to the cinema? Most of them don't even notice there's a movie on.
I'd rather they SHOUT! The whispering makes me want to literally rip my head off and throw it at them.
The man with the bald head.
He always sits two rows in front of you. He blocks your view (especially if you want to watch the movie). You can try move seats, but he always ends up in front of you.
And there's something about a bald head that attracts your attention. You keep glancing at it every five seconds, as if one of the film's characters will appear on it to deliver an important line of dialogue.
