You have a gift for understatement.
Since I was the OP, I suppose I should weigh in. None of those rules would cause me any problems.
But there's a lot more going on than just the way they impact me. Note that the header says the rules are "...to ensure a safe and satisfactory experience." That's not valid criteria. Range rules exist to ensure safety and very little else. The way you run the rest of your business and interact with customers determines if the experience is "satisfactory" for the customers.
The first two (prohibiting open shoes or open tops) are semi-reasonable. After that, the things listed are far less defensible.
"Extremes in apparel or jewelry"? How can jewelry be unsafe or disruptive? Did Mr. T visit the range one day? This one, along with the "Undergarments...muscle shirts" prohibition simply make no sense other than reinforcing a management/owner attitude of "My place, my rules." I'm really not comfortable doing business with control freaks. Or is there something more going on?
"Clothing or jewelry displaying" (if I may paraphrase) "anything we don't like". Translation: "If you're not like us, especially if you have the temerity to put your views on your clothing, we have an excuse to throw you out." What are they going to do, refuse service to anyone who shows up wearing a Pink Pistols t-shirt or a NORML t-shirt? I can guarantee that there are plenty of idiots who find the whole existence of those organizations offensive. So where's the list of what they consider "offensive or disruptive"? Or do they just get to make it up as they go along?
Finally, the big one - "Sagging pants. ..."
Holy. Cow.
Everybody knows exactly what "sagging pants" is code for. There are more issues involved in that prohibition than all the others put together and none of them reflect well on the management.
Dress codes are not needed at shooting ranges beyond an optional suggestion that closed collars and maybe a hat to keep brass from going down the back of your shirt are a good idea.
A dress code at a shooting range that transparently seeks (as this one appears to) to exclude identifiable groups is beyond stupid. "His range, his property, his rules" and "We reserve the right to refuse service to anyone" do NOT hold up under the law when the policies in place appear designed simply to keep out specific, statutorily-identified, federally-protected groups.
I don't care if I'm sharing the range with gangsta-thug-wannabes or 400-lb transvestites in gold lame' mini-dresses and fright wigs. If they do something unsafe, that's what range officers (and observant fellow customers) are for. But in this day and age, posting rules that pretty clearly translate as "We don't want any customers who don't already look like us" is an open request for legal hassles that no business owner should want. That's why I found their existence so surprising.
Clearly, I'm in the minority here (feel free to flame; I'm a big boy) but that's my take on it.
Sagging pants is code, alright. It's code for "too stupid to dress himself." I'm not some grumpy old curmugeon - that crap was big in style when I was 19-20 years old. It looked idiotic then, it looks idiotic now, and it marks whoever dresses that way as less than intelligent.
You're trying to say it's a race thing? You have to be kidding.
For the shirt logo thing, there are kids going to the range. Have some decorum while you're there. Heck, have some decorum whenever you're in public.
Again, who cares if it's needed; it's their damn range. If you want to dress like a thug, go someplace that allows it. Just don't complain to me about how horribly unsafe that range is when it's crowded with mouth-breathers too lazy to take the stickers off their hat and put some curve in the bill. FWIW, I don't care what the law you reference says, and it doesn't matter. Oh, you might feel better when you get the range you hate shut down for telling you how to act on private property (that law is so blatantly immoral), or you can start leveling threats at ranges over it. But guess what they're going to wind up doing? They're going to shut the range down.
Then where are you going to shoot, smart guy?
