I feel pretty uncomfortable
vaping in public restaurants, theaters, stores, etc. only because e-cigs, PVs and APVs are beyond people's understanding, unfortunately. They barely have any understanding of cheap cig-a-likes and think it's "water vapor" and generally don't know what PV and VG is. Too many people associate it with "smoking" and I personally think it gives vapers a bad name to try and go above and beyond what's socially accepted right now only because most people are rather ignorant of what it's all about. Smoking and the whole cancer thing gets people charged up and irritated so anything remotely resembling cigarette smoke will just add fuel to the fire.
I will feel more comfortable when truthful information is spread around so people already know what I'm up to when they see me toking on a long silver cylindrical tube (Vamo), especially if I'm in doors where smoking cigarettes is forbidden. In other words, all it does is creates confusion in people's minds. "Is he smoking or his he doing something illegal? What is that?" I don't personally like drawing this type of attention to myself in public stores, restaurants, etc. I will, however, vape OUTSIDE in public. That, I don't care about. And if it bothers someone, that's unfortunate and I'm sorry it does (also sorry to say, but I have to draw the line somewhere) they can technically go somewhere else....there's plenty of atmosphere to go around outside.
As far as stealth vaping is concerned, I will vape in a bathroom with no one in it or will vape until I get to a door of an establishment. The most I will do is exhale a plume on the way into shoprite or something but won't continue because of the aforementioned reasons.
