A Fishy Situation
This landlord is, unfortunately, finding himself in a situation that would not be easy to resolve. He posted a question online, asking if he can ask his tenant if he can stop cooking fish past 10:30 since the stench is affecting his living situation. Although he technically could, it would be super unethical.
You should be able to cook whatever you want in your home whenever you want to. This is a situation that the landlord is going to have to fix himself by investing in some scented candles, incense, potpourri, or air freshener. It’s not easy being a landlord when tenants you don’t like do anything wrong.
