Okay, I've got to chime in here .... I am the only one in my family who doesn't smoke and I can't stand the smell either but I do believe in everyone's right to do what the want as long as it doesn't impact those around them. The difference between smoke and the aroma of food as someone mentioned above is that the smoke gets in our clothes and hair as well so even if we leave the area, we still smell it. We have to shower and change clothes to get away from it. Smokers do not smell this because it is already in their hair, skin, breath and clothes. I have chain-smoking parents and two siblings that smoke almost as much and I've seen the way it has aged them, not to mention the breathing problems.
To those of you trying to quit, I pray you can. For those courteous enough to limit it to smoking outdoors, I thank you.
My best to all ...
