From THE LOCAL (Germany):
The Rhineland city of Bonn is now requiring sex workers to purchase a daily tax ticket from a vending machine to walk the streets. As of Monday, prostitutes had to pay the charge of six euros before they start their business, regardless of the number of customers. A notice on the machine defines the prostitute’s working hours with bureaucratic efficiency: Monday to Sunday, 8:15 pm to 6:00 am. This is the first such vending machine system in Germany. Dortmund also requires street-workers to buy a tax ticket, though it is on sale in nearby petrol stations, rather than vending machines.
