Laws include property rights. (Not that that franchisee would get my business, of course.)
Yes, I understand that business owners have property rights, and I understand that it is not illegal for someone to post signs banning guns. My point was, and remains, that the laws of Arizona do permit carrying guns, so “abiding by the laws” should do the same. I don’t consider “not technically violating” to be exactly the same as “abiding by”.
