It is pretty typical to go into a restroom that is used by food handlers and see a sign reminding them to wash their hands.
If a person is not attentive enough to wash their hands after using the bathroom without a reminder, are they really the type of person I want preparing the food I am going to eat?
I was in a restroom the other day and I saw, what to me was, one of the more amusing restroom ‘wash your hand’ reminders. It read:
MAKE THIS A HAND WASHINGTON STATE.
