I love the Alamo Drafthouse.
Oh, and last time someone decided to text message during a movie (not Alamo Drafthouse), I got this sudden urge to pee, stood up and "accidentally" knocked the phone out of their hands, then "accidentally" stepped on it. Whoops.
Although there was some teenaged punk sitting behind me once who decided to make an actual phone call during a screening of the Star Trek reboot (again, not the Alamo Drafthouse). I would have been perfectly fine if he had gotten up and walked out of the theater, but no, he decided to carry on his rather loud conversation right there in the theater... for all of a minute. I stood up, turned around, grabbed his phone, told the other caller that he'd have to call them back, then hung it up. He was, of course, rather indignant that I DARED to interrupt his phone call, but he didn't get a chance to say anything before I laid into him. Using my command voice (those who have been in the military know what this is), I told him "TURN YOUR <expletive deleted> PHONE OFF INSIDE A THEATER. YOU ARE RUINING THE MOVIE FOR EVERYONE ELSE. YOUR LACK OF COURTESY IN THIS THEATER IS AN ABOMINATION AND A POOR REFLECTION ON WHAT YOUR PARENTS SHOULD HAVE TAUGHT YOU." then threw his phone in his lap.
As the theater cheered, the projectionist stopped the movie and a couple of employees came in to handle the situation. I got booted from the theater along with the kid, but it was so worth it.
