Bravo man.
Latecomers really grind my gears. If you're thinking of coming into a film 20 minutes after the films started (not the trailers), then please wait for the next one. Keep yourself amused doing something else.
Yep, the weak bladderers too. Sit near the exit. The amount of times i've seen the same people, up and down the stairs, sometimes 3 times in the same film! Don't sit halfway to the back so you're up and down the stairs...or just stay at home. There's always the option of an empty bottle, then everyones happy.
Back of the seat kickers. Get some spacial awareness, for goRAB sake. One way to annoy a whole row of people.
And kiRAB. It's not funny to start talking loudly during a quiet bit or shout 'boo!' when there's a tense moment in a film.
What with the price of a film nowadays, i think vigilante justice will have to be served.
