Bet you would'nt call me a moron if you sat next to me in the 340 over the Pacific and I said that I think outlawing drugs is'nt solving the problem. Bet you would actually rub your chin and think twice before you come up with the word moron.
In the interests of CRM calling your colleague a moron is not good etiquette so with that option not available I would probably get out of my seat and take the newspaper and go for a crap. Mind you I never believe what I read in the paper but it would be far more sensible than listening to this twoddle.
