it’s definitely best to skip the air dryers, but i dont think this is a good argument for not washing your hands, especially depending on what exactly you got up to in the bathroom. i think it’s best to just wash your hands (for 20 seconds with soap and water) and then dry them on your shirt or something.

also this is slightly unrelated, but the “germs flying everywhere” thing is also why it’s best to always close the toilet lid before flushing whenever possible. especially if you have some tooth brushes lying around.
