See how that works for you, if it is so easy. While this is only one anecdote, when a local restaurant chain put up a 30.07, I asked the manager about push back. She said two old toots had tantrums on the first day and that was it. There was no drop in business.
If the signs do go up at the WalMarts, HEBs, Targets or other major locales, that will be a major unintended consequence of loss.
During the first CHL period, lots of ghost buster signs went up all over. It was only the move to 30.06's that took some of them down. Now the 30.07s seem to have broken the bias against ugly signs. Antis will push for them.
It has always been a strategy to make carry such a pain that folks won't do it. If you have to leave your gun in the car, repeatedly that is not good.
While a diversion, I always opposed businesses being able to ban carry. The MUH PROPERTY RIGHTZ don't trump the right to defend yourself. If you are open to the public, you don't take away their rights. You expect the public to pay taxes for the police and fire to come to your joint. Why should we pay for that if you take away the right of self-defense. Have your 'rights' and put out your own fires and deal with crime yourself.
