In Kentucky, we can carry even in businesses that post things similar to “No Firearms” - the only thing the law requires is that if for some reason they “identify” that you are carrying and ask you to leave, you have to leave - but beyond that, there are no legal ramifications.
“ask you to leave, you have to leave”
The thing I wonder about these kinds of rules is if it makes a diff if the store space is owned vs leased.
I.e., if you have your own gas station, it’s sort of like a private property thing.
But if you lease the space, you’re not the owner so can’t really make rules like that, though the mall or building owner could.
