Agreed. People are used to cells that are more-or-less harmless, and tend to assume that what works for an AA works for an 18650. Then we have the idiots who argue for pulse ratings and the like and give those who don't know better the impression that any safety advice is controversial or over-the-top. And there's the fact that humans are just plain lousy at evaluating risk - if you get away with it once, or fifteen times, it's obviously perfectly safe always and forever.
I would hope that the average vape shop customer has been versed on battery safety, although I wasn't advised years ago when I bought my first mods. If there's liability with a rebuildable in a vape shop, then battery safety should be covered at point of sale, IMO.
Maybe new customers should buy electronic mods with an internal battery as a first device.
