Re: Look out
"Smoking where you eat in public is generally not acceptable"
Nor is farting. Mine clear rooms. So I don't do them in enclosed spaces or where people are eating. A well ventilated public bathroom is adequate. Except when at home [in which case I'll lift one leg and lean, and laugh afterwards, or maybe poot out 'shave and a haircut' for laughs].
So yeah. So maybe vapes can have an obnoxious smell, like some perfumes, and bad intestinal gas, and your neighbor's dog when he doesn't clean the crap up for a while. But there are no known lingering aftereffects that I'm aware of...
[minor irritations are everywhere]
