What you do is snatch the cell phone out their hand, throw it across the room, busting it into little pieces! This is from someone who has recently written a book, is on television quite a bit as a conservative commenter, and by the way, is a fan of concealed carry permits for firearms. (short bio here)
Anyway, having done this, you then go on the most reputable conservative website around, National Review Online, and write an article preening yourself for your no-nonsense problem solving ability ((linky here for the goodness) (5/14/13). To set the scene, he's at a play:
... The lady seated to my immediate right (very close quarters on bench seating) was fairly insistent about using her phone. I asked her to turn it off. She answered: “So don’t look.” I asked her whether I had missed something during the very pointed announcements to please turn off your phones, perhaps a special exemption granted for her. She suggested that I should mind my own business.
So I minded my own business by utilizing my famously feline agility to deftly snatch the phone out of her hand and toss it across the room, where it would do no more damage. She slapped me and stormed away to seek managerial succor. Eventually, I was visited by a black-suited agent of order, who asked whether he might have a word.
In a civilized world, I would have received a commendation of some sort. To the theater-going public of New York — nay, the the world – I say: “You’re welcome.”
There is talk of criminal charges. I will keep you updated.
Now, it would seem to me that a person who wants people to pack heat as much as possible should be able to control himself when confronted with a boorish theater patron. But, hey, I'm only a cartoon.
