Sign=No Business from me
If I see a sign, I do not patronize them. There are enough places that I need to avoid due to federal law, that entering an establishment by choice with a sign that says no one in here is armed and ready to defend themselves, to me, just doesn't seem logical. Banks, federal buildings, schools, hospitals, -there are plenty of other restaurants or whatever that will not question my rights to carry. Those other places are inconvenient to disarm and leave it in the vehicle, I don't need another one.
