The thing is, you still have to have someone collect them even when they’re in their proper spot you just don’t have parking spaces that could have had a car them filled with a shopping trolley, or trolleys rolling off and hitting parked cars. You also make that trolley guy’s day better by not making them have to pull the trolleys from places they aren’t supposed to be.
I used to work at a supermarket and agree that the trolley collection was by far the best job but I still hate those motherfuckers that leave their trolley just anywhere especially in otherwise valid parking spots.
