+2 Internets for me, seeing the title - and automatically knowing who would be posting and how they would be doing it.
as far as the OP - ignorance and greed.
I was at a card game the other night, vaping happily (per the host's permission) ..and some dude that works at Home Depot got all frothed up, saying how he is the head of the "anti-vaping policy" at his store and how if he sees anybody doing it, he kicks them out (bull****).
I pressed him about why, and it was clear that he was completely ignorant on the subject - and was simply towing the company line. He's also a smoker, so he was probably jealous that he had to go outside for a smoke, while I didn't.
