My husband has cerebral palsy. When he lived by himself he never returned the carts. Because he physically could not. He used the cart as balance to get to the car. If he took it back, he'd have nothing to use as balance to get back to the car.

But how'd he get inside with no cart? He wasn't taxed yet from walking and shopping and could get to the carts to use as balance. He also hoped other people would leave a cart out nearby so he could grab that.

These days we go in, grab an electric for him, and we return that for him once he's in the car.
