I think it changed with tipping screens on Square POS. Many states were pushing businesses to accept EMV payments and deprecate cash back in 2017 after Apple Pay became ubiquitous, and Square was the easy to use up-and-comer in that space. Flipping a screen and asking the customer to do a thing couldn't be beat. Starbucks was quite late to "press the tip button to continue" culture. I think they added that to their payment flows in 2021, in fact.
