A Kentucky man was getting annoyed with a boy behind him who was kicking his seat during a screening of Star Trek Beyond.
A combination of moviegoers and theater employees escorted the man from the theater and were there when police arrived.
Apparently, after the man in question swore at the kid, asking if he was going to continue kicking the seat, the father got involved and an actual fight broke out.
In my experience, a dirty look from an angry adult usually stops these things before they escalate further.
