In a few short years tip option defaults have gone from 10/12/15 to 12/15/18 to 15/18/20 or 15/20/25, and some are even higher now. Some people get annoyed while others it seems will tip whatever they are told.
We have a local restaurant that we normally eat lunch at maybe once a month. Their Tip screen now shows 25/22/20, in that order. As if to say that 20% is the bare minimum and makes me feel like I'm being cheap. I'm so annoyed about this that I am finding myself less and less inclined to dine there.
My favorite restaurant has 15/18/20 which I find somewhat more reasonable.
