Wow, I'm pretty surprised to see hand washing turn into a Ford v Chevy debate. I definitely do not want to split bread with a dude that just opened up a dirty door handle, grabbed and pulled out his junk, went to the bathroom, and then opened the other side of the dirty door handle... and then touched food I was about to consume. I'm not a germaphobe, but the above is how a lot of illnesses/food poisonings are spread. Physicians/staff washing their hands is the #1 thing a hospital can do to cut down on nosocomial infections... pretty sure you'd expect them to do so before offering you any treatment. Hand washing after the restroom is a common courtesy... just isn't as common as it should be.
