After banning smoking in bars and restaurants, New York is tackling what many see as another major public annoyance. From April, requests to switch off your mobile phone before a play or concert begins will be backed up with the threat of a $50 fine. Anyone making a call, talking on their mobile, or even being rung during the performance will be breaking the law. New York is believed to be the first major US city to bring in such legislation. But Mayor Michael Bloomberg opposed the move, saying such a law would be impossible to enforce. He had tried to veto the law, but he was overruled by a 38-5 vote in the New York City Council.
