We used to go to the movies every week, but now we rarely go. I have no tolerance for people who talk during movies. Fortunately, I get the headphones for the hearing impaired, and crank them up to drown out anything but the movie dialogue.
We go to Harkins theaters, which also have a strict cell phone policy. I once was at an afternoon show with a grand total of 5 people in the theater. A middle-aged guy (looked like he was supposed to be at work, but opted for a movie instead) pulled out his phone and started checking e-mail. I walked down two rows, tapped him on the shoulder and said, "If you don't put that away right now, and leave it in your pocket, I will take great pleasure in having an usher throw your rude self out of here." He put it away, and didn't bring it out again.
(Mr. AZC hates it when I do stuff like that . . . but he's used to me and knows I'm going to do it anyway.)
