^^^ I never said he was a SS. IMO, he was just very irresponsible to go to a gun range with little or no experience and as he was removed, the business thought so as well. Rules are posted.
This range does allow you to shoot their weapons and will assist you in doing so, but this man was using his own firearm....in which case, he needed to know at least the basics before ever coming there.
Someone like that is a danger to himself and to others on a range. He had zero business being there without, at least, another person who was experienced or taking a safety class and beginner class.
I know nothing about gun ownership but if I decided to take up the sport, I would assume that a gun range would be the place to go. I might in fact buy a gun and go to the range which I would assume would be a good place to get lessons or experience.
Nothing you have written shows me that the man was anything other than inexperienced at gun ownership and trying to gain some practice in a safe environment.
If the rules were posted, why was he allowed onto the range in the first place, don't they do a licence check or something?
Possibly it seems obvious to you as an experienced gun owner but to me his actions seem fine. I'd go to a gun range long before I'd start playing with an unfamiliar gun in my house.
Given your spelling of 'license', I'm going to assume that you are non-US. In the US, possession of a gun license only authorizes you to buy
a gun. It means that the authorities have run a background check on you and there is nothing to prohibit your owning a gun (things like conviction of a felony would deny you the license.) You do not have to take any sort of classes on gun safety and maintenance in order to get the license, or demonstrate any knowledge of same.
However, I do agree with you that the gentleman in question probably thought that such things were
taught at the gun range, or that they could tell him where to take them.
