In the Oktoberfest "tents" in Munich they had 3 'rooms' Men's, Ladies, [each with an entry fee] and the pisser. The Men's and the Ladies were private. The pisser was just a double wide open doorway with a screen a few feet inside. It was only troughs attached to the walls of a long narrow room. Guys went into drain some bier, and VERY often their lady friends would accompany them. He would stand there relieving himself and they would be conversing about, who knows what!
Besides the coed nature of the place was the fact that all the guys had been drinking bier for hours. Not just drinking bier, but munching on large white salted radishes. Meaning it was often EXPLOSIVE in there. The were occasional impromptu farting contests in several languages! The pisser could hold a hundred or more guys and were always full. Surprising they didn't have their own weather in there!
