“Well, in every State in which I’ve had a CCW, you were prohibited from carrying in bars...”
In AZ you would be allowed to carry a concealed weapon into a bar provided: you have have a valid Concealed Weapons Permit, did not consume alcohol, and if the bar allowed it. If you violated one of the three you would be in big trouble.
There's a lot of wiggle room on that one. While consuming any alcoholic beverage is an automatic fail for carrying, the notice must must be posted properly and legitimately so you can know. And in fact out-of-staters enjoying constitutional carry can just say "i didn't see the sign" and get an automatic free pass.
I noticed a Changing Hands bookstore in Phoenix had a proper sign posted by the front door, but no liquor license next to it. They had a separate restricted access section in the back with a bar and tasting room, liquor license posted but no proper sign next it. This is not a legal notice, and if you're carrying, you don't have to say anything or do anything as long as you don't drink. I don't bother pointing it out either, not my call to make sure they get it right.
