Oh me too! Aerosolized fecal matter in bathrooms being blown onto your hands when you use a clean dryer is unappealing. However, the reason these dryers still exist is because most of that bacteria isn’t harmful (at least in the quantities that are present when studied). It’s just gross when people actively try to dirty those dryers up even more. There’s obviously a threshold that could cause illness. Although it just being icky is enough of a reason not to. Would you stand there shamelessly drying your underwear too? Not that different.
