I had a friend I introduced to shooting. He claimed to have been an Air Force MP and hadn't shot since his Air Force days. I gave him a safety course and let him borrow a Colt 1911 to shoot. He really enjoyed his first outing on the range and he was indeed a safety conscious shooter. It was a pleasure for me to see that he enjoyed himself so much. I supplied the instruction, gun, ammo, and targets. At the end of the outing, I took my gun back home and cleaned it along with the one that I shot.
The following week he called and wanted to go back to the range. Once again I supplied the gun, ammo, targets, etc. All he did was pay for his own range time.
The third week he calls and wants to go back to the range. While at the range I said to him if he enjoys it so much, he should consider getting his own gun, buy his own ammo, cleaning kit. etc.
That was the last time he called to go shooting with me.
