   An Emergency Call Centre worker has been fired in Toronto much to the dismay   
   of her colleagues, who were unhappy with her dismissal.   
   It seems that a caller dialled 911 from a cell phone stating, "I'm depressed   
   and lying on a railway line so that when the train comes I can finally meet   
   Allah."   
   To which the call centre employee replied, "Remain calm and stay on the line."
