yeah my mint vape in the bathroom with no visible vapor is the issue not you grown adults that still wear axe like middle school boys, or refuse to take showers or wear real deodarant
Honestly, I was at an indoor event with live music just this past weekend. They had a fog machine (a real one, that's not a metaphor), and I saw at least one person get up on stage during one of the performances, and in the middle of the performances, they whipped out their vape and took a big rip literally in front of hundreds of people, including staff at the facility and everything. Nobody gave a shit.
If you're just sitting in a corridor and chugging on a vape, I'm pretty sure someone will care, but if you take the odd puff, and you're not in people's faces about it then it's unlikely anyone will give enough of a shit to say anything.
Aside from that, I want to amplify that there is a residue from vaping, it is very little compared to cigarettes or any other combustible tobacco/nicotine product. I usually notice it the most in my car. It makes the windows look almost oily....
I wouldn't say it's particularly difficult to get off of the surfaces, after all, e-juice is water soluble. I'm not saying it's easy, just not hard, especially if you compare to the tar from combustible tobacco products...
