Answer 1

No one washes their hands perfectly, there are too many little crevasses and folds and such to get all the dirt and germs off even if you do the full 30 second routine (not to mention that most people scrub for like 5 seconds). So there’s still dirt and germs on your hands after washing. When you dry with a towel, you scrape some of those dirt and germs onto the towel along with water, which is a perfect environment for the germs to multiply. Add to that the ambient germs floating around in a bathroom and you’ll build up germs on a damp towel very quickly.
