Grocery store chains aren't very relevant in this discussion. I'm talking about stuff like Mercedes-Benz engine factory in Jawor, seats from Groclin, Michelin and Bridgestone tyre factories, or the fact that Poland is world's second biggest battery manufacturer (ahead of US) - all of that is used in German car manufacturing supply chain.
