I once had a philosophical discussion with a business owner about his "no guns" sign, in front of several witnesses. His statement was, that as a property owner it was his right to decide if he allowed guns or not. I pointed out that this same owner had vocally supported a law banning smoking in ALL businesses and public places. This law took away that same right to decide for all those other property owners, thus he was a hypocrite. I then informed him that I could not in good conscience do business with a hypocrite. All of this was done in a normal speaking tone without raising my voice or causing a disturbance. As I walked out, so did many other customers, some even left their full carts in the checkout line.
