At a little country church, we attended on Snake no nook snek shirt. So a huge black snake was in the men’s toilet. My husband was very strong but said it was difficult to pull it out. Don’t they put a screen to prevent them from coming up? I recall the Army Engineers did something like that bc snakes and rats was prevalent. Normally snakes don’t bother me but if there was one in my toilet I would be concerned. We have a septic tank. That snake would have had to tunnel through cement. That would be terrible seeing a snake in your toilet or anywhere in your house! Just like guns. Live by snakes die by snakes. He should just look for another profession. This one is the avenue to death.
