Sounds like you've been to a coupe places I know all to well... No matter your experience/credentials/equipment, they treat you like crap and over-charge the crap out of you. Basically, a crappy experience.

I was recently introduced to the clays sport and have found Bull Run Shooting Center to be a blast (pun intended). Its in the manassas battlefield park, so not to far out. Their sporting clay course is affordable, and well set up. It offers some freedom in that you and your friends pull your own targets.
There are, of course, some rules to be followed: only load 2x, #7 1/2 or smaller shot, 23" barrel minimum, and the FOUR GOLDEN RULES!!
SAFETY FIRST & HAVE FUN!
