A New York theater is trying a new technique to get audience members to turn off their rage-inducing cell phones. Staffers at the Brooks Atkinson Theater noticed that the public had become fairly immune to a simple prerecorded announcement asking for the phones to be shut down, so just before curtain, they’ve begun playing an obnoxious recording of cell phone rings so realistic that people all over the house dive for their phones in horror. “And so a new front may have been opened in the long, hard war against the rude and the clueless… With some of those people, polite appeals are a waste of time.”
