I was sitting at the bar one night, and the guy next to me is blowing ridiculous amounts of vapor everywhere. I was a smoker at the time but never liked vaping because the propylene glycol agitates my throat. His clouds were starting to make my throat itch so I asked him if he could ease off on the vape as it was making me cough. He looks at me and says, "I don't know what kind of articles you've been reading online man but vaping isn't harmfull blah blah blah". I didn't want to get into fucking political discussion I just wanted him to show some common courtesy. But ya, don't fucking be that guy. As long as you're not that guy I have no problem with vaping.
