There's more to it than laziness. I am fucking lazy and I always return the trolley. You have to be also selfishly unconcerned for the experience of your fellow man.
The only time I don't return the cart is if I see a cyber truck parked on the way to my own car. Then I leave the cart in a spot most inconvenient to the cybertruck owner.
While I no longer have the responsibility of collecting carts, I still work in the grocery industry and I appreciate your courtesy. I'll never forget the agony of rounding up and pushing dozens of them through the snow and slush of a Kmart parking lot. I can't believe I didn't do more damage to my body then. Now it's just the cement floors that are slowly doing me in.
Cart narcs, our lord and saviour
