It is unsanitary for a cook to not wash his hands after using the restroom because he could potentially contaminate the food he is cooking with bacteria and other germs which would be harmful for people to consume.
Context: I saw a cook today not wash his hands after using the restroom.
Hypothesis: I saw a cook today who did not wash his hands after using the restroom and it made me feel very reassured about their hygiene

Given this context, is the hypothesis true (Yes/No/I don't know)?
