I am pro-"cart abandoners deserve the gulag", but we've also gotta recognize that some disabled people may need the cart for balance, and if they return it, they now have to walk across the parking lot without that crutch. Maybe the right answer is to put cart returns next to disabled spots?

If someone hasn't made a garbage collector for C and called it C Shore, they need to get on it asap

What an incredibly bold claim with zero evidence to back it up.
