I am long out of the picture by the time the movie hits the theater but they do make cell phone jammers..
And what bothers me more is people at movies who eat. WTF?!?! Did you go to the movie to watch a movie or have fucking dinner? I can't stand listening to them sip their giant drinks and stuff their fat fucking faces with popcorn and chips.
I like the jammers but don't mess with my snacks! You're going too far! I almost never move my straw all over the bottom while sucking to try to extract the last drop of coke.
