As far as tipping out I am afraid that you can't control that. As much as you might like to. Servers tip-out because others provide service that the server doesn't have time to (cleaning tables/making bar drinks). I wouldn't tip more or less based on restroom cleanliness that is more just good business/the law. The only restaurants I know that servers tip out hostess are ones where the hostess provides a service to the waitstaff other than seating (rolling silverware or taking to-go orders)
