Eat Happy in Düsseldorf

I had a nasty case of food poisoning; a colleague who works at a bakery said that if they find the boxes in the store, they'll just put them back in the refrigerator.

Not sure what's the point of having separate staff for this, it's just regular old frozen packaged sushi. Not that there's anything wrong with that... But the REWE could just sell these items without having an "Eat Happy" nested inside it. It's just odd.
