Madame Marissa did not want her slave to be perfect because she knew he was not and he would never be. But she wanted him to try. She felt he was not trying and that was not ok with her. She had to do something to make sure he learned his lesson and that he never pissed her off again. So she crushed some dough with her dirty hiking boots and she made him lick her soles and eat the dough from her boots. She then warned him against laziness.
