Thinking outside the box here:
Are they chalking tires at the pumps, or just in the parking spots? Park at a pump, maybe even leave the nozzle hanging out of your tank, and they'll never suspect a thing!
I have been pumping gas and gone inside for a "quick" (by Bucee's standards) purchase and come out and the gas nozzle has been taken out and put back in the pump and my gas cap put back on.
I think they're even onto this scheme.
