In the local Aldi, it's not bored kids - it's usually unhoused folks who don't particularly have any other way of making money. Pushing carts around the small Aldi parking lot isn't a great way to make a living, but it presumably beats shaking a coffee cup in the middle of an intersection or walking around the entire town collecting plastic bottles or aluminum cans.

I'm sure they don't make much, but it's more than zero.
