Which is my point... asking the guard if he is acting on his own or as an "agent" of the owner/management is a fair question.
Its pretty safe to say that the security guard is an agent of the property owner. Otherwise what good would he be? And that means even if he is acting on his own, ie they have no firearm policy but told the guy to leave. It was his opinion that the complaining customer was more important than the armed customer.
He was still acting as an agent of the property owner.
Your only recourse would be to talk to the owner/manager and if they want to allow you to carry weapons on their property they need to inform their agents.
