You are all over the state OPS. Sorry to hear about your most recent encounter. I had a customer tell me it was illegal to open carry when I had mentioned it to an employee of Jackson Arms once. I corrected him but he remained adamant that a CA Fish and Game Code made it unlawful. I knew what he was referring to, but had to leave it at that since I had guests who were waiting for me to bring them something to shoot.
Seems like everybody knows everything as soon as they enter a firearm establishment.
