The Aldi I usually go to has staff that are so ridiculously efficient that there are nearly zero empty boxes on the shelves, and the rolling "box cage" is nearly always tucked away somewhere unseen unless they're actively using it.
This isn't a complaint. It's a nice place to shop, and the stock is always very orderly compared to some other locations.
But GFS? They've got boxes at the checkout. I think the expectation is that the customer is supposed to box their own stuff, but they always do it for me if there isn't a line.
Their hardgoods tend to be tremendously high-quality for the price, too: Stuff is frequently ~half what I'd expect to pay elsewhere for something similar. Their buyers must be stellar.
It meant that when all other supermarkets stopped offering free plastic bags, most of the shopping populace was already used to keeping reusable bags in their cars or purses, so it was a pretty easy transition.
