As I said, Aldi’s and a few other store chains use the coin and chain lock method of ensuring the carts are returned. I suspect the brake locks are more expensive, but are less of a cultural inerta barrier to break.
When I was a kid in the '80s and '90s, I didn’t see either method of ensuring cart return. We just went around the lot and returned all the carts because it was something to do while out mom was in the store. Technically I think we were supposed to stay in the van, but we got bored easily and using the carts as scooters was fun.
