Mistress Cassandra does not like stingy people and she realized that this guy was one. She had to find a way to punish him and make him understand that it was not ok to be stingy. The mistress used her bare feet which were stinky as well as her converse shoes to do it. The shoes were dirty and also smelly. He was degraded and though it was hard for him to change suddenly, he started making baby steps.
