The cart deposit might be a German thing. Aldi is German and in Germany you will be hard pressed to find any store (not just Aldi) where carts don't require a deposit. It's been a thing so long that most people seem to have little plastic chips instead of having to use coins like us tourists.

Also notable that most cashiers in Germany seem to be sitting (again not an Aldi thing).

What's an Aldi thing I guess is that they export these things to other countries they go to.
