Goddess Mel was mad at her husband and she was ready to walk away. But he begged her to forgive him and she decided to humiliate him first before she forgave him. She wanted the humiliation to be public and she made sure it was. He knelt before her in public and poured her champagne. She made him use it to lick her feet clean before she made him continue with the same indoors.
Goddess Mel does not like anyone being late to pick her up. She likes to keep time and when anyone keeps her waiting, he or she has to pay for it. This guy was late to pick her up for an event and when he came, she had to punish him. She made him lick the soles of her shoes in public. She did not care how humiliating it was or who saw him do it.
Goddess Mel stepped out of the car and her feet got dirty. She stepped on dirt and she was pissed off. She made her slave lick the dirt off her feet before she could get out of the car completely and go where she wanted. She was wearing sandals and she did not want her feet dirty. And if they got dirty at any point, he was responsible for cleaning them up.
