When I lived in Las Vegas we were warned about "inciting a riot" if we were to scare some old lady in a tourist town. My class covered everything from what to wear, how to act, what to say as well as when, where and how to shoot. They covered different holsters, different guns etc. They even had a sims shoot house we had to go through.
But after 10years of packing in multiple states I have gotten lazy sometimes. I dont even care if Walmart sees it anymore [ROFL1] Course in 10 years I have never been asked, checked, harassed or even noticed that I can tell. Even my Grandma can hug me without knowing.
