"Everyone's a winner," explained Regina Goetz, a former prostitute who runs the "Maison d'envie" (House of Desire) brothel in Berlin's Prenzlauer Berg, a district in the former East Berlin, which is a stronghold for the ecologist Green party.
"The environment is a topic on everyone's lips and it's pretty difficult to park around here. So we came up with the idea of an 'eco discount' of five euros to anyone who leaves the car at home," Goetz told AFP.
"The crisis has slashed our turnover in half over the last year," the 56-year-old told AFP over coffee and cakes - flanked by scantily clad prostitutes.
But the green discounts have proved a roaring success and have business back on track, she said.
