Throughout the day your hands accumulate pathogens and chemicals that can cause you and others disesase and of course they also accumulate oil and dirt, etc. It is not suggested that we wash our hands everytime we go to a bathroom because something terrible happens everytime we go in the bathroom and touch our dicks and if we don't wash our hands we'll instantly die, but just to ensure that a few times a day we are cleansing our hands to maintain good hygeine for our own health and the health of the public. It's no different than, say, automobile manufacturers that suggest you check your tire pressure everytime you go to the service station: it's to ensure there is a regular schedule of prevention and maintenance.
