I went for the body combat class at 22:00. The full of lights gym had a queue of 30 people to enter the classroom. Inseide several from previous class stayed. 30 guys, maybe 20 girls and a class in chinese. In the changing rooms while not all showers were taken (they are covered with courtain), the queue for specific one. In the sauna I stepped to the 2nd floor and everyone starred at me. I believe I shouldn’t have put the feet on the 1st floor. And of course they never show them naked. On the way back I mistake in the train and went to different line.
