Yes. Because tipping is based on personal service and tradition.
I hear people say "tradition" when we talk about tipping, but traditions change. We don't have to stick with something just because it's been the tradition. A lot of people are expecting some kind of tip nowadays, which wasn't the case in the past. Some have mentioned inflations raising the price of food by 30%, etc, and 20% of that is steeper than before. If you look at tips as handouts, some kind of charity, (most likely, in the old days, single mothers and such used to waitress), then, I can see why people want to keep on doing it, and it makes more sense. It's like spreading the joy, I guess. Nothing is wrong with that as long as the system allows it. (Obviously, you're not allowed to do the same when a really old-looking man who takes the bus and works at Home Dept two days a week to make the ends meet carry your paints and get them ready for you, etc. Or a young friendly lad who works some afternoons after school to pack your heavy groceries into your car.)
I do actually tip even at buffets, but usually only up to 15%, but I no longer go to buffets. I used to not tip for takeouts but I do now (15%). I give more (sometimes a lot more) for DoorDash drivers, etc. I think it's perfectly fine to not tip at all though. It's not like those states with less than full minimum wage for servers are requiring customers to subsidize the server's pay. I think servers are only required to report 8% of the gross sales (so anything over 8% is tax-free money), so 8% is the amount IRS expects the tip to be. If 8% of the gross sales plus the server minimum wage do not meet the full minimum wage, the employer is supposed to give the servers enough salary so their total amount reaches the full minimum wage. At least that's my understanding, so yep, everyone should do whatever they want regarding tipping (including not tipping).
Personally, the tip options are annoying when you see them in business establishments that shouldn't be asking for a tip, but I've never been the person to be pressured into doing things, so I'd just mark 0%. I would have a problem if they got rid of that 0% option though LOL.
