Don't smell the shampoo: 10 things that everyone does in the supermarket - and are forbidden. Shopping with your own bag or reading newspapers and then not buying can even be a criminal offense.
For hygiene reasons, customers must buy these as soon as they touch them. If you purchased too much food or if you don't return it, you have no right to return it. Unlike technology, goods cannot be exchanged in the supermarkets in the general way like clothing or goods like money. If these are found, they must be handed over to the supermarket operator.
