Kaufland and Co. make an announcement to customers: The food giant explains which action makes you liable to prosecution.
The rules for supermarket shopping can be found on the pages of the regional consumer centers or at Stiftung Warentest. Customers are allowed to open packaging - under one condition. But food and newspapers are not the only products that customers can try or "test" in the supermarket. The situation here is similar to that of newspapers. Every now and then you can also find products that have already been opened.
