We were in the Pergamon Museum in East Berlin, just a few months after the fall of the wall. The young woman with us was walking around, enjoying the artifacts, but bottle-feeding her baby at the same time.
Bolting from the corner of the largely empty room, a small but sturdy East German security lady hurried across the room to inform our friend that under no circumstances could she walk around the museum and feed her baby at the same time! When we asked politely what the problem was, she just simply repeated a little firmer and louder that it was verboten!
