What does this make the folks who take the carts off the property? We have a grocery that has installed wheel locks that activate when they cross a line under the pavement.

Apparently that doesn't work very well so the police have a video camera system, on a trailer, complete with flashing blue light, watching your every parking lot move.

There was also a grocery in my old neighborhood that removed the cart corrals and had an employee walk you to your car and help load it up and took the cart back inside. That system lasted, literally, three weeks.
