If that tough looking guy wasn't lacking manners, it would have been funny if he was the sauna master. However, considering he's so filthy, he obviously couldn't teach anyone anything.
That's a damn full sauna. It's even packed in two dimensions, not just in one with a long bench on two or even three walls. To be honest, I would skip a sauna like that if it already had five other men present. No way I'd sit in a sauna feeling like a sardine in a can.
