Years ago, I visited a shop that had a short firing range in the back , where you could rent and fire automatic weapons . The front counter customers often pointed or even dry snapped pistols in the direction of the range area, thus pointing at the shooters on the firing line . When I got ready to try an MP-5 on full auto, I suggested to the range owner that he enforce some safety rules. He tartly replied that he had a business to run and would have to spend all day teaching if he tried that . I replied, " But it is my ass...! "
I agreed to cool it, fired a few mags of 9mm, and left with lighter pockets .
Years after that, the Feds got that guy on drug charges he said were bogus and they closed him down .
One gun shop owner told me he was ready to throw a customer out for unsafe handling but buttoned his lip . I told him he needs to learn how to be assertive . Examples :
1) Aggressive : Do that one more time and...!!!!!
2) Passive : [ says nothing ]
3) Assertive : " Sir . You aren't handling that gun safely . Point it in a safe direction at all times . If you haven't had formal instruction, may I recommend a good trainer ? "
