99% Of The Way There

I was out shopping today and observed a woman unload her shopping cart into her vehicle and walk the cart over to quite near where the carts are supposed to be returned to. But instead of turning the cart so it would be in line with the rest of the carts, she just left it in front of the line. She was 99% of the way there. Why the hell didn't she just turn the cart? I don't understand going to that much effort and then to stop at the very last possible moment. Odd.
