My rules for taking my wife shooting are simple. I know what I'm doing and she doesn't. This means that my rules are THE RULES. She does it my way or she doesn't go, unless she goes by herself. When I am present I am the king. Unless we are at a controlled range where someone else is the king. Even then I am the Prime Minister and I call all shots not called by the RSO
If we were ever out shooting and a situation like the one you describe occurred I'd pack up the guns and take her home. If she refuses to get in the car she can walk.
I've been married for 15 years.
