I work in a doctor's office. Proper sanitizing is my job because it's part of patient care. Like one of the people I work with is responsible for counting how often I clean my hands every month. If she doesn't "see" me clean my hands a minimum of 40 times, I can get in trouble.
In my personal life I wash my hands before cooking/eating, after I use the bathroom, after changing diapers or cleaning up puke, and when they need it.
