At a fast food reastruant

I was at a friends house tonight. He told me he recently went to a "well known" fast food joint. He went to the mens room. While washing his hands, he saw an employee come out of the stall and proceed straight to the kitchen- thats right the employee did NOT wash his hands.

My friend, when done, walk out to the dining area - and spoke (loudly) that an employee did not wash his hands after using the facilities.

1. Would you have made such an announcement.
2. If not, would you have told the manager?
3. If hearing that announcement, would you:
a. leave
b. eat anyways.
4. Other comment.
