There is now something named The Shopping Cart Theory which tells your or others if you are a nice person.
"To return the shopping cart is an easy, convenient task and one which we all recognize as the correct, appropriate thing to do. To return the shopping cart is objectively right.”“There are no situations other than dire emergencies in which a person is not able to return their cart. Simultaneously, it is not illegal to abandon your shopping cart. Therefore the shopping cart presents itself as the apex example of whether a person will do what is right without being forced to do it.”
I rather like this because I see people in grocery/Walmart/ Home Depot etc, just leave their carts next to their parking spot and leave. Most of us have learned to get the cart to the corral, but I'm always shocked at where not so nice people will leave their cart when leaving the stores. Too often they leave it in the empty spot next to their car, or in front of the other car. Most grocery parking lots have quite a few cart corrals and if you can walk all over the store pushing that cart you can walk it 15 feet more to where it should go.
Also, those who do go to the corral, but put their small cart in the large cart slot and vice versa, drive me crazy too. Anyhow, there is probably no changing many people, but I do push wayward carts into the corrals if I see them. I wonder if any of the people who don''t do what they should with their cart ever wonder if the store parking lot has cameras? I bet they do.
