When I was a lad my dad taught me to shoot. By that I mean he taught me the mechanics and a respect for what a firearm can do...no specific safety instruction. He was a WWII Gunner's Mate and I doubt that they had a very regimented safety training program during WWII.
My time in the Navy (mid-late 70s) afforded me the barest minimum of firearms training; nothing that could be termed safety training.
I had the desire, but none of the wisdom. As a new firearms owner I visited public ranges. I made a few minor transgressions and was barked at in no uncertain terms by ROs.
A lesson well learned is long remembered.
My pride was bruised, but I sure took those lessons to heart. I made damned sure not to repeat those errors, and did not hold it against the RO or the sport. May just be a coincidence
but I am still alive and still enjoying the sport many years later.
There is a huge difference between a volleyball coach and an RO. A transgression in one activity carries the risk of the loss of a point or a game; the other, the loss of a life. Maybe your own, maybe someone else's.
These consequences must be clearly understood by all concerned, and communicated clearly and
immediately.
Entirely too many people today have no concept of the consequences of their actions (think of how any people leave their kid to bake inside a car and cry crocodile tears, or kill someone else while driving drunk/texting/other negligent behavior) and get their "feelings" hurt over being held to account to their actions.
I have never had occasion to bark at someone doing something unsafe at my local indoor range. Thank God.
That said, I am too old and have too few days left on this Earth to worry overmuch about someone's "feelings" if he/she does something demonstrably stupid/negligent/dangerous in my presence.
