I feel like you can tell a lot about a person by what they do with their shopping cart in the supermarket parking lot.
-Leave it right where it is and drive off: entitled, self-absorbed and probably living some sort of immoral lifestyle. Not to be trusted. Likely your typical lawful evil battle mage.
-Put it in a cart receptacle inside the parking lot: Responsible citizen, obedient to the dictates of society.
-Move cart to any kind of parking lot island: chaotic good. Will strive do the right thing, if not by the exact letter of the law, then in essence.
-Bring cart all the way back into the store: goody-two-shoes. This person was likely the kid that reminded the teacher if they forgot to assign the class homework. Lawful neutral.
-Steals cart: The social safety net has failed this person multiple times.
