Well, one brothel, at least, and it’s in Berlin, Germany. Maison d’Envie is knocking off 5 euros ($7.50) off their regular 30-minute, er, sessions if guests present their bus or tram tickets or their bicycle helmet to prove that they took other means of transportation to get to the brothel. The owners of Maison d’Envie (a mother and son tandem, egads, not to be judgmental, but really?) think this setup is loads better for everyone, since they lack parking space, plus it’s eco-friendly too. Ah well, anything to hike up, er, sales and help clean up the environment, I suppose.
