Where did they work that it was OK to search the car? That is illegal in most places without consent, probably criminal even.
Concealed is concealed if it is legal, I could care less what they post.
One way they get around it is that since Georgia is a "Right to Work State", they ask to search you vehicle. If you refuse, they terminate your right to work there..
Kinda walking the line, but the other way is that since you are on their property they have a right to search your vehicle, again if you refuse, you are terminated.
I know Georgia Carry is working to overturn those provisions, Let's hope we can.
