I always flush the toilet in public after a poo because I'm paranoid that someone will smell the "devils present" i left behind

I never really noticed or cared about toilets not flushing properly in my life, but my uncle always made me go check to see if my poop had flushed because he said it was rude to leave your stinky present in a public restroom for the next person to smell. I always thought it was weird, but the mental image of a poop that looked like the "devils present" has haunted me my whole life, so i literally flush every toilet 5 times in public after a poo
