I don't even like handshakes. I've seen countless people leave the restroom without washing their hands. Some people get offended if I won't shake their hand.
I am not a germaphobe at all (I'll eat food off the floor if it falls), and I agree 100%. The non-washing of hands is endemic.
Fist bump to the rescue!
