Little old ladies do that with shopping carts as well.
I caught one doing that to someones car. She was too lazy to take the cart and put it where it belonged, instead shoved it between two other cars, leaving a scratch down the entire side of one of them.
Being a good citizen, I took down her license number and gave it to the car's owner when he showed up. A few months later a received a bottle of whiskey. Apparently he had her charged for causing willful damage and sued for damages.
Being old is no excuse for being ignorant and damaging other peoples property.
