Stock Photo - 03 June 2021, Brandenburg, Potsdam: A napkin case with fork, knife and spoon and the imprint ""Fancy an aperitif?"" lies in a restaurant next to a smartphone whose display shows a negative Corona test result. The new Corona rules for Brandenburg's gastronomy have led to annoyance in many establishments. That's because, as of Thursday, the testing requirement for patrons in outdoor restaurants is only waived if the host does not offer indoor seating. In view of the sunny weather, many establishments have therefore decided, according to a dpa survey, to initially only offer seats on the terraces.
