Did any of them compare the concentrations of carcinogens in the cigarette smoke a smoker inhales via the cig in his mouth, and the concentration at a pub or restaurant table 3 metres away, with good normal pub ventilation, (if it's not good it could be made to be good and that could be enforced) ? If it wasn't good, if it was smoky / smelly I wouldn't go there.
I don't smoke BTW, and one good aspect of the ban when it came in in Scotland (where I frequently work) was that if the place was half decent the landlord usually had it redecorated / cleaned up.
But by and large the only think that got up my trumpet about smoking in pubs/restaurants was the common practise of females at the next table to hold the lighted cig with their arm outstretched at an angle of 150 degrees from straight ahead, IE behind them, without looking what was there, because they didn't want the smoke in their own face, or contaminating their own food and their own clothing. Somehow this behaviour was regarded as acceptable, "Chic" even, sort of "Hollywood
- Esque". Thinking about it a small aerosol sized fire extinguisher (I now have one redundant from an earlier car) could easily have been used to discourage that practise.
