Sometimes, you will walk into a public bathroom and actually find one that looks relatively clean, although doing so often feels like you won the lottery after looking in a about eight consecutive stalls with urine covered toilets or bowls filled with brown water and/or feces. I don’t know if women have the same issues in their public bathrooms, but men’s public bathrooms can be absolute total nightmares to deal with.
That means the toilet seat, the flusher, the sink, the hands dryer, and the door handle on the way out. This is why you really should have a small hand sanitizing gel container with you so that you can clean yourself after you leave the bathroom. After all, what is the sense of washing your hands well and then getting contaminated by the door when leaving?
