The freebie grab did have me annoyed as well. The first thing that makes me wonder about this story is that the person was "walking into the restroom" when he noticed the employee walk away from a urinal and not wash his hands.

The person confronted the employee about washing his hands, and when given a reply, didn't goto the bathroom or wash his hands, or whatever he had come into the restroom to do, but instead followed the employee back out into the restaurant and watched him go into the kitchen and back to work.

So, either the person just goes into bathrooms for no reason, or they let the employee out of their sight for the duration of time they were in the restroom doing their business, and so their story is suspect and most likely just a grab to get free food.
