A man comes in and uses the latrine, he then grabs the water knob and turns the water on, contaminating the knob, he then pumps the soap dispenser with his other hand, contaminating the soap dispenser. Then he scrubs his hands under the water. Then he turns the water off, re-contaminating his hands. Then he grabs the paper dispenser lever to feed paper towel out, contaminating the paper dispenser lever. The next person to use the latrine and the same sink will cross contaminate himself and the things he handles to wash up. That ain't gonna be me folks.
