Reply #172: You must have missed where I said "air quality standards."

There was no attempt whatsoever on airliners to keep the nonsmoking section smoke-free, and an airliner is one large room.

Separate smoking and nonsmoking rooms with separate ventilation can certainly be done in a restaurant at reasonable expense, and systems can be certified and air quality standards enforced. That is not hard. It doesn't satisfy the moralist urge to make smokers pariahs, though.

And FWIW, I hate cigarette smoke; it gives me migraines. But I'm not a fundamentalist about people smoking where I can't smell them.
