19. Do not have conversations inside viewing theatres!

For the love of god, do not talk inside the viewing rooms!  Other people are trying to actually watch what's on the screen.  Just don't be that rude jerk, people will thank you for it.  Every time someone pulls out their phone and starts texting or begins talking loudly to the person next to them, I want to punch them in their damn face.  Please, don't be the person that finally pushes me one step too far and instigates a face punching event.
