As a kid, I almost missed a flight while hunting luggage carts at the airport.
I'm sure they don't make much, but it's more than zero.

This. Soda bottle deposits when I was a kid.
(Heck, even now. Who am I kidding? My state doesn't have them anymore, but I still vacation in places that do, and I still keep an eye out for bottles and cans.)
That's what incentivizes you to take your quarter back. I keep a quarter in my car's center console for Aldi and getting a new one is a hassle.
I suspect that if you are going to be shopping at Aldi, you're planning on shopping there and it's not a random one-off, so you already know about the quarters and bring one with you.
Aldi is nice for quick stops because they aren't that big, they have most of what you might want but it doesn't take 30 minutes to get through the store like Kroger.
I try to keep a quarter in the car, but it often ends up in my pocket after I return the cart and I forget about it. I should drill a hole in one and put it on my keychain. But it won't be too long before we don't carry keys anymore either.
My car has an Aldi Quarter stashed inside that my family knows never to spend. It is only for Aldi shopping carts. I joked with my kids once that my Aldi quarter was older than them and that I've used the same quarter for the shopping carts since before they were born. They called my bluff at the checkout of course.
In my view it's quite an inconvenience: who carries quarters around anymore? I rarely have any cash with me, let alone loose change.
I expect we'll soon see something where you make a small payment with your card or mobile pay app which is rebated when you return the cart.
