History sets the context for the present and knowledge of the past helps us predict and shape the future. Accordingly, although I am neither a historian nor futurist, I share what I know and think about these issues in this concluding chapter. The upshot is that we know little about the global origins of tipping, but more about the history of tipping in America. Tipping was rare in the U.S. outside of major cities prior to 1840 and did not become common until after the Civil War, when wealthy U.S. travelers to Europe supposedly brought the custom back home with them. The custom was widely opposed and was even briefly outlawed in several states, but rapidly took hold and evolved with the customary restaurant tip in the U.S. increasing from 10% of the bill in the early 1900s to 15% in the middle of the century, and 20% at the end of the century. Recent increases in tip-flation, tip-creep, and tip-fatigue raise questions about the future of tipping, so I explain why I believe that tipping is unlikely to ever be abolished in this country.
