There's always been a good amount of debate about when it is and is not appropriate to vape in public. Some enterprising individual decided to take things to the highest authority on etiquette and asked Miss Manners what her take on the situation is. The response was an interesting history of smoking in society. Apparently, smoking jackets were once used for smoking. But, in the end Miss Manners is pretty harsh when it comes to the modern day equivalent.
You ask about your public image. To those who recognize electronic cigarettes, you would appear to be someone struggling to give up smoking and therefore relying on a crutch. We have come to the point where that is considered pathetic, at best.
But not everyone does distinguish the real from the imitation, particularly at a distance from a speaking platform. Such people would not consider you pathetic, you may be relieved to hear: They would consider you evil. The now-accepted rule against smoking near nonsmokers is perhaps the most dangerous one to break. People will excuse heinous crimes before condoning that.
Ok, for some reason I'm inclined to not pick on the advice. Maybe because it's bad manners or something. But the real reason is that in reading the article, the author laments the lax social decorum of the 1930′s through 60′s as compared to the more refined Edwardian era of smoking. Me? I just want a vaping jacket. That should totally become a thing.
