Risking her personal safety, this woman confronted him and shot the whole thing on her phone. Without so much as raising her voice, she embarrasses him worse than a family stumbling across Blue Is The Warmest Color on movie night. He apparently becomes so ashamed he destroys the photos by biting the flash card in half. I do not know what she's saying to him, because it's in Chinese, but it's clearly so cutting he hides his face until the next stop and then runs away like the rich villain at the end of a college frat movie.
She stuck her neck out for the good of us all and used her superhuman shaming abilities to get this unmitigated dickwad to run off with his tail between his legs.
