Maybe, that one time. But if it gets the word out that the theatre /does not tolerate/ cell phone usage during a show, and that you really /will/ get kicked out if you do so, then it should make for less distractions overall for regular/repeat patrons in the future. I fucking hate people who use their goddamn phones during a movie, because of how insanely distracting their bright screen and bleepy feedback noises are in an otherwise most dark and sometimes quiet room. Heck, I would gladly sit through one of these fuckheads being noisily ejected from the theatre simply because they've /already/ ruined my enjoyment of the show, and deserve nothing less. That it will hopefully make phone use less likely in the future is just the cherry on top.
