smoking
just leave the cockpit when old smokey lites up!!..probably most airlines have a post 911 requirement to replace a crewmember with a flight attendant when one leaves....you don't get smelly, he gets to smoke, and a step or two closer to the flight ops office if the f/a cops him in...which is all self imposed!!......unless of course the f/a likes a puff up stairs, but you're not in the cockpit so who cares.....
