Pepsi is a panzy corporation. Only real German children drink Coke. Apparently adults are not allowed to drink anything without caffeine or alcohol. Let me tell you a little story about water. It is never served at restaurants.
Mineral water is carbonated water.
I hate mineral water. Then you get charged DM 4.70 for it. Apparently it is offensive to serve water to a guest. Also, the only water fountain I have ever seen was in a museum. There is of course that little issue with the absence of slices.
