Not one person has to tip anyone for anything.
Tipping has nothing to do with the 13th Amendment. And you do have to tip sometimes. I could take you to several restaurants in the resort town where I live that have signs as you walk in and clear messages written in their menues that a 12 1/2 % service charge is added as a gratuity on your bill and the suggestion that an additional gratuity can be added if the patron so wishs. But you are going to pay that 12 1/2%. If you don't you will be arrested for theft of service. These restaurants have been in business for many years, they are very popular and often have long lines waiting to get in. The owners don't care if you never come back. They prefer it. They will have the magistrate tell you in court you are not allowed to go back, ever. You will agree in court to pay the service charge or spend time in jail. You will pay a fine too.
The exception is that if you have a complaint about the service or meal, and you discuss it with the management, your service charge will be waived and you might get the meal for free. But you have to do that when you pay for your meal, or better yet, during your meal.
It's not tipping, it's not a gratuity, it is surcharge.
