Two weeks ago, I was in a fairly vape friendly pool hall in my home town. I play poker there. I was discussing my recent drop in nic level to a smoker that has expressed an interest in converting to vaping.
From across the room, one of the other players literally YELLED, "There's NICOTINE in that?!?!"
I said, "yes" and tried to explain the science behind vaping. It was too late. I asked him if he wanted to see the studies which show there's nothing to worry about as he jumped out of his chair saying something to the effect of, I don't appreciate the fact that I'm breathing that in!!! He was about 30 feet away from me in a room with (at least) ten foot ceilings and I had not been blowing huge vapor (I've learned it's best to be discrete.)
As he stormed up front to complain, I went to my car to get my iPad and printed materials, just in case.
A couple minutes after I returned, he came back with his proverbial tail between his legs, not saying anything.
When the manager came back to take my drink order, I asked her if R&$@ had spoken to her about my vaping. She said, "Yes, and I don't think he was happy with my response, but until the FDA regulates those things and we're forced to ban them (like smoking), or until 90% of our customers complain, you're fine."
I replied, "OK, good...I was going to leave if I was going to be asked to stop vaping, but since I'm not being asked to leave, I'll have a beer."
She asked that I not blow huge clouds of vapor and not 'rub it in his face.' I told her I wouldn't do that...I really am a pretty nice guy.
Some of the other players later mentioned to me that he totally overreacted. I just shrugged and said, "yeah...it happens. I just hope he doesn't have to sit next to one of the (many) smokers...there's probably more carcinogens coming from their shirt than he would ever get breathing in my vapor!"
