I fucking hate it when people don't return their carts, and yes I always slide them in and condence the stack as much as possible. I used to have to do carts while working retail, and I would have to pick up so many carts that people just left on the curb or even in parking stalls. Some of them wouldn't even return them when right next to the corral, and instead just block an entire parking stall.

The worst was working carts in the 100°F+ heat. I had to take breaks every 15 minutes or so just to avoid heat stroke, and while resting I would see these people just leaving carts in the places I had just cleaned up. Infuriating.
