Thought it couldn't get worst than NSFW mahjong moony man? It can't. But this, this is pretty damn close. Here, a gentleman is standing and up and stretching in front of a mahjong game. Remember it's okay to enjoy yourself in Japanese game centres, just don't enjoy yourself in Japanese game centres.
