Some people just like to complain.
Case in point. I am at the outdoor range and my friend shows up and he is shooting a Ruger MKII. The range is pretty empty except for the two of us.
Guy comes in and sets up on the right of my friend and we have been shooting for at least half an hour.
He gets a warm brass down the neck and flashes the evil eye at my friend who is oblivious to what is going on. Mind you there are 25 or so stations at the range. You can tell by the look on his face that he is getting upset.
Two more rounds and the guy comes unglued. He gets in the face of my friend.
My friend moves to the other side of the bench and rigs a brass catcher and the problem is solved. At least for this visit. I have seen the guy before and he is always wearing a sour puss.
I just avoid him, but he walked into the problem.
Sometimes people are just looking for a confrontation of some sort.
Just remember, those same people drive...
