I'm a simple emigrant and I don't pay much attention to price tags in grocery stores

So I didn't even notice that at the checkout here they tack on the cost of the bottle itself for each bottle. That is, you buy water for 15 euro cents, but you pay 40. When you're done, you can come and return these bottles to a special machine that will issue a coupon. 25 euro cents for each, then you can collect the money at the checkout or pay with it right here. #money #Ordnung
