I saw a good example of this a while back. I was standing outside of a restaurant that was open to the street. There was a guy in the middle of the restaurant, kicking back after his meal who whipped out an e-cig and started huffing these huge clouds of vapor around his head, like it was a blunt or something. Just total "look-at-me" behavior. The people around him were completely dumbfounded. Everybody had stopped what they were doing and turned around to stare at him. It looked like nobody even knew what to do. He was definitely the kind of guy who would have insisted that he was completely within his rights to stink the place up with his cherry cola juice because there wasn't a NO VAPING sign in the restaurant. Thankfully, I didn't have to deal with that guy, but you know there are thousands like him.
