Annoying Autofrühling

Went to the town centre of Braunschweig today for the annual "Autofrühling". The city is crowded with exhibitors of mostly new cars, usually presented by car dealers. There is also a vintage corner. But some of the folks passing by mix up vendors and vintage enthusiasts and think "it's their right" to touch and test the old cars as well. Made some very annoying experiences there today and left early!
