I try to avoid ranges at any busy times. Usually I go to Deer Creek on weekday mornings, or parabellum at lunch times.*
I haven't witnessed anything expressly unsafe at parabellum but I'm not comfortable being there with someone renting a gun and having explained to them how a SA firearm works. Saw a young man who clearly didn't know how it worked being explained to at the counter as I was leaving.
That's one of the things I like about Farmland. I'm usually alone. If there's any one else there, as often as not it'll be a board member or one of the old guys. Zero safety problems.
