Local circle k stores in north Louisiana have signs that say no guns allowed in the store. They make them very small about 4" X 4" and post them in very hard to see places. It is state law to abide by these signs, so, I consider this method of signage as a form of entrapment. Anyway I'm sure that the intentioned robbers will change their mind about robbing the place if they see the sign. I'll drive an extra mile or two, to another C store rather than spend one dime there.
