Seems the two German supermarket chains really like to have the same infrastructure everywhere. Everywhere I go the Aldis look exactly the same. They have slightly different products depending on the country. But the price tags, interior, ... is basically the same. Okay and we don't have "Flaschenpfand" everywhere... (deposit on the plastic bottles and the machines where you can return bottles.) I bet all of this makes it a lot easier for their techs and management. And it could also explain why they sometimes redo a store that still looks fine and fit it with the latest shenanigans.
And as an aside: I've shopped in the first Aldi store ever. It's not far from where I live.
