A couple of my favourite small garages I visit, allow smoking in their showrooms and werkshops, 'cus they hate roolz and dictation. 
Half the boozers here ignore it ......till some toss-pot ex-pat wanker complains,,,
in the summer I was smoking outside, a couple at the next table asked me to stop smoking....

we were sitting on the side of a road......needless to say I fecking ignored their request.......
