I saw a place post a tiny quarter sheet of paper with like size 12 font summary in the corner of the store front. They don’t mention it anywhere else, but the POS system still has the tip option for you, and only then do they offer a receipt so you can see that you just paid 20% more Edit: I don’t recall if they even offered a receipt https://lemmy.world/pictrs/image/7a3f2ca8-68f9-4b05-836d-b529061c58ff.jpeg
