Bike to this Berlin brothel, get a discount

The feed store where I buy organic layer feed for my backyard chickens offers me a 10% "human-powered transport" discount if I pick up my order on my bicycle. As I bike around town happily (and slowly, chicken feed is heavy), I think, everyone should offer a discount like this!

Evidently, my desires have some sort of uncanny telepathic power, because in Berlin, a brothel believes the same thing. Everyone should get a discount for showing up at a business via bike. Even if the order you're picking up is, well, you know. Something that doesn't really need to be picked up, more lifted... ok, I've said enough.
