Mine does. He's adamant that as water from the tap is clean it stands to reason that anything that regularly has tap water running through it is also inherently clean. Sinks, showers and baths should all be magically self cleaning without the need for human intervention. He does concede that toilets might get grubby. By extension he also thinks towels should never need washing because you're always clean when you use them. It goes without saying that I completely ignore this bollocks. Can anyone beat that?😂
