You chose the worst example in the list, because Belgians are famously the butt of “haha they’re dumb” jokes, getting it from both their French and Dutch neighbours (maybe Germans too?).
I’d pick the Danes since they’re typically seen as a more evolved people.
For France, it just makes sense tbh.
I’m guessing you’re French based on your instance. I had a friend many moons ago that worked at a processing plant where they packaged the William Saurin stuff (cassoulet, etc). At some point during the batch process once they reached the quota for the branded batch, they literally just switched the label roll to the Lidl ones and kept going with the exact same food.
Of course there’s no way to really know which products are like this and which are made with nasty cheap ingredients.
