This guy was a snob and mistress Khali did not mind it. What she did not like was how he wanted her help after all his snobs. She felt that he had to come off his high horse and she helped him do it by torturing and humiliating him. He did not know what she had in store and was shocked when she spat on him and trampled him too.
Mistress Khali wanted to make this guy scream and that is why she used her cigarette. The mistress forced the guy to be her human ashtray and she forced him to do the things he had never done before such as to be trampled using high heels. That is how he realized he had messed with the wrong mistress and he tried his best to get her to forgive him.
