The Alamo Drafthouse is a Texas-based theater chain known for their witty PSA about not talking or texting while in their theater.

They will throw you out, so you’ve been warned.

Director Richard Linklater was in Austin, Tex., promoting his new film Boyhood, and on behalf of the Drafthouse, offered frustrated moviegoers some advice — albeit violent — on how to deal with those moviegoers who just will not put away their darned phones! (Who knew he used to be a trained assassin?!)

Seriously, don’t do this, ok? :)
