+ 1 for Olkofri,thats the way to go,I do driving and so far all is good in that matter though I have noticed some companies prefer them drivers shouldn't be smoking in vehicles so that that may be the question of a time how long it takes before one whos is not obeying to employers rule gets fired,some time it would never happen.Then another place where I'm doing my causual driving is our local morticien,then when driving with the client' on board and flag-banners halfway down I think It might be advisable to refrain from smoking my pipe,don't you think?
