shopping carts ???

where do you put your shopping cart after you load your car?

i was walking back to my car as i watched this lady push her cart out of her way ao she could back up. she let the cart continue rolling till it hit another womans car. which ended up leading to the 2 women arguing about being a responsible adult teaching thwir children to "put shit back" 😂😂😂

anyway after that little lunch show, i thought id ask you guys, do u put your shopping carts back, let them loose in the parking lot, or at least try to park the wheels up on the curb to at least keep it from rolling
