This guy was too grumpy for mistress Dula to deal with and she told him that he needed to sort out his grumpiness. But the poor guy did not do what she wanted him to do and she chose to humiliate him in a way that he had never experienced before in his life. That is why she trampled, crushed and humiliated him. He got the message she was sending.
Mistress Dula was pissed at the fact that this guy misled her. She hated the fact that she was misled on purpose. She had to teach this guy a lesson and she did it with her trampling and with her boots. She did it with the help of her friend. It was a lot of fun for her and she loved the way it all went down. The guy realized he should never mislead anyone as it could come back to bite him in the ass.
