Stop asking permission and CC anyway? If it's actually concealed worth a damn no one will be the wiser. Granted I don't know any of your state laws, nor if the building has a "no firearms sign". If it does and you live in a state where signs carry the weight of law then you might be better to go somewhere else. If there isn't a sign, or your state doesn't carry the weight of law. Carry anyway and don't ask for a permission slip.
