It's also how every supermarket in the neighbourhood in Barcelona I lived in worked. You could either buy pre-packaged produce (like two apples in a styrofoam based covered in plastic) or go to the produce section and point at what you wanted and an attendant would place it in a bag, weigh it and put a sticker on it which would scan at the register. Another thing I hated about many European supermarkets were the one-way gates at the entrance (like subway turnstiles) and the only exists through the registers. Walmart started doing similar during Covid but at least you could exit through self-checkout.
