A while back I was getting car rides to a couple doctors. To these kinda regular visits I most of the time had the same person driving. The first time I get in someone who I don't knows' car, I don't vape, or even ask to vape. There is no way I would even 'subtly hint'.. So less than but close to 30 minutes into my first trip with this one guy in particular, he asks me if I mind if he smokes! Mind you, he's already shook a cig 3/4's out of a softpack and he's got every intention of doing so, lighter in his hand too. I said no, and before I could appear just as polite and ask if he minded if I vaped, he had already lit his cigarette. Of course, I already had my mech at the ready.. Probably 5 or 6 round trips with this guy and while he appeared to be quite interested in this thing, and in a pretty good chunk of the whole thing, in the end he was still a (cough, coughing) cigarette smoker and he had never expressed to me a desire to switch.
