As I said, .. I don't think much of an individual who would knowingly and intentionally carry a firearm into an area that does not belong to him while having full knowledge that the person, or authority in charge of the property has prohibited it.
Would I ask during an interview?.. No, I would simply make a common sense effort to apprise myself of what written rules are available. If they have no policies or rules and nobody has made me aware of any particular prohibitions, that's a different story.
I will carry a gun where is it not prohibited.. if I am aware that the person in charge of the property does not allow guns then its a prohibited area. I don't care if it a rule, a policy, or law written in stone tablets. If its more their place than mine, I will respect their right to set conditions. Its not much deeper than that and I have always offered a measure of respect before expecting it from others.
