I once went to a public swimming pool in Austria, half the pool was for nudists and the other half was for clothed persons. The restroom for clothed people was very long, but the restroom for nudists was busy but short. I ended up going to the nudist restroom and a 50+ year old naked guy walked up and started talking to me while using a pissoir. Basically he was asking why I was dressed at the nudist portion of the pool, I told him the line was shorter, he laughed, and went about his pissing.
