I see nothing wrong with this. I'm a non-smoker but I don't care of others choose to smoke ... it's not my business. But here's my problem ... too much of the smoke makes me sick ... literally. My sinuses swell up like I've got a cold, I get a headache, and sometimes I'll start sneezing. Next day, I feel downright hung over.
When I go to a restaurant to eat and I ask for a non-smoking section, that non-smoking section better darn well be smoke free. Nothing like sitting at a table that is supposedly in non-smoking while just on the other side of the lattice-work "wall" there's a table of 4 and all of 'em are smoking.
The separate sections need to be more separate.
I am a non-smoker also, and I would never tell a smoker he could not smoke. However at the same time I do not appreciate smokers tell me I have to tolerate having to breathe their smoke. And yes to much smoke can make you sick. Especially if you have a cold. It's very hard to breathe then. As far as I know the smoking sections in our restaurants here in my town are very well separated from the non smoking sections
