Am I ignorant about this range rule or has range become too Jerseyfied ?

[ett]

A couple of weeks ago I won a new toy in a raffle; a S&W 9mm Shield Ported.
Today was the first chance I had to take it to the range and fire it.

The local outdoor ranges to which I have a memberships; were both too congested for my liking and it was starting to rain.
So I went to the local indoor range; Heritage Guild.
Since obtaining a membership to the outdoor ranges a couple of years ago; I don't go to Heritage more than 2 or three times per year.
And the last two times I've gone to Heritage. I've had some interactions with the range officers that gave me the feeling it's becoming too (for lack of a better vocabulary) "Jerseyfied".

The last time; before today; I went there. I had a range officer begin to give me a talking to about laying down, on the bench, a Pietta 1873 SAA "without it's cylinder open".
It took a couple sentences of me correcting him that these Colt SAA clones; or the real thing; do not have cylinders that swing out.
All that can be done without disassembling the gun; is to open the little loading gate. Of which mine was open.

Today when I went there. I was opening carrying my Taurus revolver on my hip as usual. Which has never, ever been a problem before; at Heritage or any other range.
One of the range officers noticed it; and began giving me their usual speech about how to remove it from my holster; strong side facing down range and placing directly on the bench.
I said yes I'm aware, and that I was not going to be shooting that weapon.
At which point he immediately said he doesn't think that is allowed.
And then turned to the other range officers asking if I was allowed in the range, with a holstered weapon, that I was not going to be shooting.
They promptly said yes it was allowed.
After which I said to him "Really ?! That's a range policy ?".
His reply was "Yes, sometimes it is."

After getting back home, I looked at their website to verify their rules.
I could not find any rule stating that you must fire holstered weapons at the range.
The closest rules I could find; which have never changed for as long as I know; are:

• All guns must be cased or holstered when not in the shooting port.
• Only one gun uncased or unholstered at any time. If two people in port, only one shooter at a time. Pass gun by placing it on shooting bench, not hand to hand.

So; is it sometimes a range rule; at Heritage or any other range; that if you bring a holstered weapon into a range you MUST fire it ?
If yes; what is the reasoning behind it ?

Or are my last two interactions with range officers at Heritage simply a case of it growing, having more patrons from NJ than PA, and possibly having more NJ range officers ?

Thanks;
