I tipped my local coffee shop three dollars, drove away with my three drinks, then discovered later they had messed up all my drinks. That was humiliating. On the other hand, somebody at our local pizza joint recently made the most perfect version of our favorite pizza we've had yet. When it was time to pay, I tipped extra and wrote a note complimenting the worker who made our pizza. That felt good and just.
