The House of Desire is a legal brothel in Germany. Ever conscious about the plight of the planet, they are offering discounts to all patrons who skip on driving when visiting their locale.
Customers need only show the receptionist a bike lock key or proof of use of public transit and voila, that 45 minute shag goes from 70 euros to 65.
The Save The Earth brigade just got a whole lot sexier. No word yet on how clients can prove they walked over.
