Since Gov. Nikki Haley signed a guns-in-bars bill, you've likely noticed something different about the door to your favorite watering hole or restaurant. Some places put up signs saying no concealed weapons are allowed, while others are more welcoming. The Taco Spot was all for firearms before the law even passed, putting up a sign that read, "NOTICE: This establishment supports the 2nd Amendment right to keep and bear arms." The sign also features an image of a revolver and a check mark next to it, as if to say, "A-OK."
