Sounds familiar...though most of the range masters are fine. One brought in his M4 shotgun for a friend and I to shoot (I think it was the M4 semi-auto) - but we go often enough that we know a lot of the people that work there. I've never had a real issue other than them being a little rude at times. But whatever, I just ignore it and enjoy the range.
yeah there's been a younger asian guy who is friendly, helpful, and pretty cool. Helped my brother with sighting in his 22 scope and he was the only grabbing brass from other lanes for me. Theres another guy who was the ruder one, white guy, wore a bandana couples tats who was giving off a im the boss and your not type personality. He was questioning everything we did. Had two lanes so i was collecting brass from both and he came up and started challenging me saying i could only collect from 1 lane not both and some other stupid crap.
Still one of the nicer ranges ive been to. bit expensive but worth it when im in the area.
