One [Berlin] bordello, hoping to stave off falling demand in the economic crisis, has begun offering discounts to customers who pedal bicycles to the door.

"It's very difficult to find parking around here, and this option is better for our environment," said Thomas Goetz, who owns the brothel Maison d'Envie, or House of Desire.
...

To qualify, customers must show the receptionist either a bicycle padlock key or proof they used public transit to get to the neighborhood. ... Those who arrive on foot, however, are out of luck.

"We haven't found a way for people to prove they have walked here," Goetz explained.
