I know that the problems I have seen in recent years are more pain and ignorance, but you really refreshed my cognition, so I will give you a good answer on how to avoid going to the toilet. First, destroy all toilets, urinals, squatting pits and drainage systems, so that people can't go to the toilet when they come to the toilet. Second, set a high charge standard inside the toilet and don't collect it from the outside. If someone sees it outside, they may not go into the toilet, but collect it inside. If someone comes in, you charge. If you don't pay, you stick to him, stare at him to go to the bathroom and keep urging him. In this case, I think he can either pay or leave, or just beat you up. Third, make this toilet fully transparent and glass, so that a fully transparent toilet can be opened to everyone around without dead ends, and you can avoid going to the toilet in the toilet; Stop it, my mind is very open.
