I want as many people as possible to spend as much money as possible at my facility. That is the bottom line for most if not all businesses. As mentioned above, I would be willing to risk losing your business. Since, .00001% of people ever OC, I would be willing to risk losing all OC as customers. That is barely a rounding error on a cash flow statement. No, I don't post no OC, and here is why: 1) I wouldn't want to risk pissing off CCW advocates, since there are a lot of them. Even though most CCW won't ever OC, they would probably only see a gun in a red circle on the sign and not read the rest. 2) I wouldn't want to risk pissing off gun owners, since many people own guns. 3) I wouldn't want my entire customer base to see a sign and wonder if there were problems with people displaying guns at my facility. As a reference, Fin Feather and Fur (Cleveland) has a sign stating that all guns must be checked at the door, the only exception is CCW. Meaning that even in a big gun shop full of gun loving customers, they don't want OC.
