> Coin for grocery cart wastes time messing around to get a quarter & lock driving away customer volume that more than pays for a young adult to push carts back.

This is a claim. Is there evidence? Especially at a reasonable wage for a human being (which is not federal minimum)?

> Leaving the items in the container wastes shelf space & time by disallowing spring loaded or gravity dispensers

Shelf space: Aldi seems to do a pretty good job of keeping everything they want to put out fronted. As for spring or gravity dispensers, I can go look around a different supermarket and the only place I see gravity dispensers is in some (not all) drink coolers and some (not all) spices. If they showed efficiency bonuses, I'd suspect that we'd see them more.

> lacks self service kiosks & usually have 1 lane open

No self-service? Sure. One lane open? Not where I am. There's usually multiple open and even when there are, with three carts in line, they call another cashier.
