If I witness this happening at my B&M, I do my best to quietly acknowledge to my customers that THAT isn't what vaping is about. THAT is a hobbyist having fun. YOU'RE just wanting to quit smoking, and it works. You don't need THAT for this to work...
I shouldn't say they are ALL like that. But it seems like a majority. As a noob, the most helpful least condescending response I got was:
"Start simple, and spend lots of time doing research and reading reviews before you start spending bigger money on impressive hardware."
Did I listen? Nope. But I still respect that answer more than any other I have gotten.
