In the late 1990's I went to visit a friend in Florida. On my first night there we went out to dinner at a little seafood place, and I was absolutely stunned when the waitress asked 'Smoking or non smoking?' In my home state we hadn't been allowed to smoke in a restaurant for many years, so it felt like time travel. We sat in the smoking section and ordered the lobster. While we waited for our food, I lit a smoke. Because I could. The smoking section of this restaurant, by the way, was completely empty. We were the only people seated there, and we were directly under a ventilation fan. Halfway through my first cigarette, I put it out. I couldn't stand the shame of it, the guilt was overpowering. I hadn't realized how conditioned I was to think of smoking in a restaurant to be so utterly wrong and horrible. I simply couldn't go through with it. I used to smoke in restaurants all the time when I was younger and it was socially acceptable, but not any more.
And for that reason, I'd have to say I'd pick the good food. I'm a proud vaper and while I know it isn't smoking, it would just feel wrong and weird to vape in a restaurant. It might be different in a place filled with other vapers, but mostly I wouldn't even wonder if it was banned or not, I just wouldn't do it.
