Don't remember coming across too many snobs at the ranges I frequented.
In fact, the guy with the Rolls Royce in the parking lot was usually very down to earth and readily happy to help a newbie out.
Tampa Sporting Clays was partially owned by Gen "Stormin Norman" Swartzkoff. (He hated that nickname and preferred "The Bear" , he was as big as a bear).
I met him many times and every time he was teaching a Boy Scout troup or youth group how to shoot, for free. He supplied everything.
He was more typical of what I've seen, the opposite of snobbish.
