You might have been swept by an overwhelming sense of annoyance, wondering when the tipping protocols changed, why, and to what end. Recent years have witnessed the twin phenomena of “tipflation” (a higher percentage ask for tips) and “tip creep” (the extension of the practice into new industries).

Some places are even embedding the option into self‐checkout kiosks—situations, in other words, where a human worker plays no role at all.
