Mandatory "gratuities" should be illegal. I normally tip very well for very good service. The amount of the tip decreases with the quality of service. This is how a server knows whether they are doing well or not. It's like immediate feedback. I've already blacklisted two restaurants where the service fee is abused. When it is just me and my wife we get excellent service but every time we have been there with a large party, the quality of service suffered dramatically because the server knew they were getting a good tip regardless. I worked my way through college in the service industry but that was before the service fee era we are in now. That also means I know better than to complain in a restaurant before the last plate is served. I don't like eating other people's bodily fluids.
