I just finished updating the Bathrooms I've been to map to include some of the bathrooms I visited on my trip to Berlin.
The thing about German bathrooms is you're often expect to pay to use them, and there's very often an attendant.
I might pay sometimes to use a bathroom, but if I'm a customer in a store, and the bathrooms isn't remarkably clean or special, I don't see the point of paying.
