you can argue the to55 all you want guys, each to there own but lets look at it from a different angle.
2 identical companies, but with one difference, company A advertise that they are a non smoking company. as a non smoker myself i would choose the non smoking company, 1) because i wouldn't have to smell there smoke from there van (and i can do, in fact i can smell smoke at traffic lights from the person in front) 2) because without all them fAg breaks they will be more productive. and 3) smokers really are a smelly lot, seriously guys, not just smoke but real stagnant smelly disgusting vomitty type smell, you just don't realise it, when someone says about smelling like an ashtray, they mean, smelling like an ashtray, and not a fresh ashtray either. them ashtray smells you get when you empty a full one first thing in the morning type smell. oh and 4) the smoking company would have to charge more to fund there habit. not cheap you know.
so i would say clarkey, if you put on your literature that you are a non smoking company, you will never have to ask people not to smoke, and you may lose one or 2 customers because of it but i would guess you'll gain more than you lose. might even try it myself. after all, i am a non smoker.
