A perfectly reasonable statement. Is there law to back it up? (Asking because I hadn’t been aware of that, and need to point it out to the HR doofs who put big bright “gun free” zone stickers on our office doors.)
I would presume that all businesses that post No Weapons Allowed stickers have previously discussed the matter with the company attorneys and insurance agent.
I doubt that the insurance policy would be a huge financial burden on any business. I mean what are the odds of a nutcase shooting up your theater?
