It's a shame that this type is allowed to exist behind the counters of stores that maintain a stock of firearms and related shooting supplies.
I've been into high-end gunstores where the knucklehead said there was no difference between rifle and pistol primers,and all powders were the same......
On more occasions than I'd like to count I've been "swept" with the muzzle of a weapon........
Ditto being handed a weapon without first visually inspecting the chamber......
The absolute worst was the "Professional" gun store where a long haired, bearded, dunlop bellied fool struck up a conversation with the wife that went something like this(I kid you not!):
"Hey there, little lady! You be interested in gettin' yerself a gun for protekshun when yer hubby ain't around? Somethin like this little S&W Ladysmith would fit you about purfect. "
The Missus replied that hubby was present (a nod in my general direction), and also stated that I and she were entirely capable of maintaining our safety, with or without the other being present.
This buffoon went on to completely make an ass out of himself, all the while attempting to loudly dispense his words of knowledge for all within earshot.
Fortunately these establishments don't last long, and are few and far between. The number of decent stores with qualified staff has improved dramatically in the past several years, and the terstosterone level has been muted a bit as well.
Not too soon coming, IMNSHO, as females make up 50% (+/-) of the population, and more women are accepting the responsibility of their own personal protection.
