I used to work in a restaurant and the manager was called on me for this once. First let me say if I were alone in the rest room I’d always leave without washing and use the wash sinks in the back since they’re better and don’t have to touch the door, but if there’s a customer in there with you always wash in there for the ‘show’. This one time I had to go really bad, so I stepped off the line to go real fast and there was a customer already in there. After I finished I waited to use the sink but the guy was washing his hands over and over. Soap water rinse, soap water rinse over and over again, meanwhile I had food on the grill which I didn’t want to burn, I waited as long as I could then I just left and washed in back, and of course the guy got my manager.
