I assume some of this comes from small businesses getting a Square terminal and thinking "Tips? Yeah sure, I'll check that box, can't hurt!". It can hurt. If I'm prompted to tip [15/20/25]% just because somebody grabbed a donut out of the rack and dumped it in a paper bag, I think less of the place and I'm less likely to come back. Thought: Somebody should cook up an "AR" app that reads a menu and adds 20% tip plus local sales tax to every price. I'm just as guilty as anybody of visiting e.g. European countries and thinking everything's expensive, but that's because the prices on the menu are exactly what you'll pay, not 70% of what you'll actually pay. Yes I realize I can just do basic mental math, but not everybody can do it, and it'd be kinda neat to point my phone at a menu and see all the prices instantly reflect what I'll actually have to shell out.
