Saturday, 4:45 p.m. on the so -called main square in the Lugner City in Vienna: The Clown Poppo has cleared the stage on time. While an employee is busy dismantling the microphone stands, half a meter under it in the atrium children ride children on oversized plush giraffes, horses and camels between the standing desks. Men with beer cans are already leaning on the desks, most of them are middle -aged, like with tattoos on wide necks. The proportion of T-shirts with slogans in fracture or metal bands is above average.
