Bollywood star AMISHA PATEL has been accused of abusing and threatening an airline worker after a friend was refused a flight upgrade. An Air India employed claims the actress was upset, used foul language and threatened to have the worker sacked after the incident, ahead of a flight from Mumbai (Bombay) to the US on Friday (18AUG06). The friend was eventually allowed to fly with Patel in first class. A spokesperson for the airline says, "We have ordered an internal inquiry to find out what happened. But what appears now is that the passenger was at fault. "A police complaint has been lodged by the employee." Patel was shocked by the complaint, claiming she planned to issue a complaint about Air India's staff's rude behaviour.
