we aren't savages.
the only time i dont put htem in the corral is if the corral is full.
But sometimes I space out when I'm with the kids and forget to park near a corral, and I've already buckled the kids in. If there's a corral nearby, I'll return the cart. Otherwise, I try to put it where it won't roll and hit a car. It happens maybe 1/20 times. But I'm not leaving the kids alone in the car while I walk across half the parking lot.
and if there are homeless nearby in need of new transportation, i will push cart in their general direction
Come to think of it, I never shop anywhere. I've outsourced that to my wife, so things just magically appear in my house.
but yeah I return the carts to the cart thing in the parking lot everywhere else. Floating carts are a pet peeve of mine since they like to damage cars (dents, scratches, etc.)
