I agree with the view expressed in the second half of pellegrina's post. I hardly know any smokers, but a favourite relation (now dead) was a heavy smoker, another relation smokes, and a few of bek's friends smoke I think, and I have nothing against any of them ;) So it's not prejudice against all smokers, I accept they have a range of demeanours in general, and regarding their smoking habits specifically. But I have witnessed enough smokers with a bad attitude (and incidentally poorly trained dogs) to be satisfied with my assessment of both situations.
