Princess Nikki does not like losers. She does not care how old they are. Whether they are young or old, she does not care. All that matters to her is that they do what she wants. She does not like to associate with them and therefore they need to keep a distance from her until she summons them. This old loser did not know that and he breached her rules. She did not care about his age and as punishment, she made him eat her shit.
