Mistress Lola does not care about the phrase respect is earned. She demands hers because she gives it to others too. When this guy was disrespectful to her without any justifiable reason, she had to make sure he learned to respect other people. That is why she chose to trample him and humiliate him as painfully as she was able to. The mistress crushed the guy and hard trample him using her boots and she was able to achieve her objective.
