This just happened, local leisure center a young woman walked into the sauna naked. Someone else immediatly said to her "you can't be in here like that love, its not allowed". She replied I'm German, this is sauna, does this offend you?. The other woman said no, but it is the rules. The naked woman then went on about how she always does it, sauna doesn't work unless your naked and everywhere else in Europe does this.
Some young men opened the sauna door, and closed it immediately when they saw her. She laughed and said back " its OK you can come in". She clearly heard people telling her it wasn't allowed and was enjoying the attention she got.
I kind of see her point about prefering to be naked, but there are rules in place and she was obviously making other people uncomfortable.
Was I bu to tell reception on the way out?
