Knew a fellow who use to take a broom handle in a soft case out his door to every gun show. If he bought something he'd leave the broom handle in his truck and bring the gun in the case and tell his wife he had no buyers and was going to put his "old" gun back in the rack. Did this for years I'm told until his wife sent him a text one day while he was at the gun show. "Please pick up a broom handle today and that case better be empty tonight. ". The jig was up. You can't fool them every time and best not try.
