Nothing personal, but how anyone could smoke while choosing flying as a profession is a testament to how addictive those things really must be. It's hard enough over the years to keep a first class medical without charring your lungs.
But on the other hand, I can't stand people that go to a bar and then whine about the smoking. That's just like my other favorite people, the ones that move next door to the airport and then call to complain about the noise.
