In the latest upgrade, the black "No Tip" button has been replaced by the gray "No Tip, thanks!" button. This button is now of different color from other tip buttons. I have MA degree in psychology, and I can attest that this small change has a profound psychological impact. When one item on the menu is of different color, it strongly entices the customers to choose this button over the others. Adding "thanks!" doesn't help either. As a result, our tips have decreased by a whopping 90% after that. There is no way to customize or remove this button. Please, please, please, go back to the previous setup where all the buttons are of the same color! And also, either remove "thanks!" or add it to all other tip amounts. I hope this is just an oversight on the developers' part and not a deliberate attempt to screw the merchants.
