Customers care about the whole package -- the location, the hours, the queue, the decor, the food, the music, the crowd. If they like it, they come back. If not, not. That's a 100% effect. The manager needs to control all of this. If they hire good waiters, you will enjoy good service. But you can't pick yours, and I don't think what you leave at the end is a particularly big lever for affecting the service you've already had.
