Years as far as I can remember, seems it hasn't got through to some people ??
Former Liberal Democrat leader Charles Kennedy has been "spoken to" by police for smoking on a train.
Police said a man was advised of the no smoking policy on the 1105 BST Paddington to Plymouth train earlier.
They were told he was smoking on board and "refusing to stop", thinking it was fine to smoke out of the window.
Mr Kennedy, who was ousted as Lib Dem leader in January 2006 after admitting to a drink problem, has long tried to quit smoking. The train manager on the First Great Western train called the British Transport Police after Mr Kennedy was discovered smoking on board, the BBC understands.
