Madame Marissa did not like anyone to be a nuisance to her and this guy did it. She was pissed and she had to teach him never to do that again. And she even went ahead to make a video of it and shared with potential losers who might attempt what the guy had tried. The purpose of it was to send them a message that they should never mess with her.
Madame Marissa took some toast and she put it in her socks and she wore her shoes. She let her feet sweat and then she removed her shoes and her socks and she had him lick her feet as well as eat the toast. It was disgusting but he did not have a say in the matter. The only thing he could do was to eat the toast, which he did.
