@4V29LN0n This is a pretty forgiving series (at times). In the chapter that introduced Shirou (in the original series), the governor closed every restaurant and was going to use his powers to coerce Shirou's mom for sex, and after he ate Mao's cooking, he was forgiven because he was just in a bad mood from being hungry. Evil chefs get punished more in this series.
@spurgleburgle It is how things were in Chinese history. Governors, officials or local authorities can only be punished by officials with higher rank or the Emperor. You can watch the drama Justice Bao and see that.
I take it you haven't paid much attention to this series, huh? People who abuse their power thanks to being legitimately miserable are given a huge pass in this series. Only people that are actually conniving get a comeuppance.
