Absolutely 100%. I tried explaining that the water inlet to the toilet diverges and is used to supply the bidet attachment but they weren’t having any of it.

To be honest though, growing up I was taught this too. That bidet is super unhygienic because you wash your ass with shit water. Remember seeing a charmin commercial too and it was like “bidet? Let’s join the 21st century!” Or something like that. I was like 6 🤷
