I'm not a delinquent and follow rules. I wish to live in an orderly society. :) It's dangerous to just leave a cart in the middle of the parking lot. What happens if there are strong winds, and it suddenly starts moving down a slight hill. It could easily crash into and damage other cars. In the U.S., we have cart racks throughout most parking lots. So, it's a short walk to return to the cart to one of those. It's not necessary to return to the inside of the store.
