I served at a restaurant that had this. Not only was the entire dining room a de-facto smoking area, despite the zoning, but it mattered for nothing if your section was smoking or not. Between the constant smell of fry grease and cigarettes, I wanted to burn my uniform after every shift. And since I was depending on a low paying job, guess how often laundry happened? :(

PSA: Tipping culture is a problem, but so are server wages. Please help 'em out; their job is miserable.
