You're at the Фильмы and the people in front of Ты are being loud, you?

I never freakin' tolerate people talking near me during a movie. It happened most recently with a bunch of young girls when I went to see The Fault in Our Stars... they were honestly making a Комментарий about EVERY freakin' single line in the movie.

So I just lean over, tap them on the shoulder, look directly at them and ask "Excuse me girls (or boys), but please keep it down, you're disrupting the movie".

Every single time it has worked, I aint gonna just sit back and just internally сука about it xP

Kill them.
Because this isn't a movie theater.
This is a torture chamber.
*plot twist*
серовато-коричневый, dun, дун серовато-коричневый, dun, дун серовато-коричневый, dun, дун . . .

Think about what assholes they are, but don't actually do или say anything.

ask them nicely to be quiet
if they insist on being annoying ..kick their seat

Kindly ask them to be quiet. If that doesn't work, try using something to try and block any of the noise they make (if possible)

The dramatic sigh.
If that doesn't work, leaning over and saying "Do Ты mind".
Third is "Shut up или I am getting the manager!"
I have never had to make good on the threat. With the price of Фильмы getting so high, I don't go and pay to listen to idiots that are old enough to know better.

Tell them to shut up, или I'll beat them till they piss blood. Failing that, I'd likely just ask to stop talking... of course, teenagers seem to be getting еще and еще obnoxious these days... the first option seems likely...
