Edeka supermarket in Germany’s Hamburg removed all foreign products from its shelves for a day to make a controversial point about racism. The supermarket just sold German-only products with the gaps displaying messages such as ‘this shelf is quite boring without variety’ while the salad bar had a sign saying ‘our selection knows borders today’ and the cheese counter said ‘so empty is a shelf without foreigners’.

“Edeka stands for diversity, and we produce a wide range of food in our assortment, which is produced in the different regions of Germany,” said an Edeka spokesman. “But it is together with products from other countries that we create the unique diversity that our customers value. We are delighted to have received a lot of positive feedback regarding Saturday’s action.”

This isn’t the first time Edeka has gone viral with its campaigns, although some of the commercials have sparked outrage.
