I'm going to limit someones toilet time
Why are you limiting someone's toilet time?
I'm going to limit his toilet time every single day
While it may be annoying to always have the bathroom occupied, you should still respect someone's privacy. Sometimes the bathroom is a safe place, or someone might need to use it for a long time. It is none of your business what they do and how long they take.
I'm a Nazi and people should not be allowed to take their time. I'm a better person than everyone else.
You should not stress how long someone stays in the bathroom. It's understandable that you may have to use the bathroom as well however it may be best to talk to the person about how long they stay in the bathroom.
