In short: Tipping is often defended as a performance incentive, yet research shows it is weakly correlated with service quality. Instead, gratuities are frequently influenced by factors like age, race, and physical appearance. Despite its roots in aristocratic social status, this practice remains a deeply entrenched, albeit controversial, global economic custom.

The origins of tipping are rooted in medieval master-serf customs, later evolving into 'vails'—money given to servants by house guests in 17th-century England. When the practice migrated to America in the 1850s and 1860s, it faced significant resistance. Many Americans viewed it as incompatible with democratic values, leading six states to pass anti-tipping laws between 1909 and 1926. Critics like William R. Scott, writing in 1916, argued that the act of tipping reinforced a master-slave dynamic, undermining the equality essential to a republic.

Economic theory often frames tipping as a solution to the principal-agent problem, suggesting it motivates workers to perform better for their managers. However, empirical evidence frequently contradicts this. Studies by researcher Michael Lynn reveal that gratuities are often arbitrary, with servers receiving higher tips based on traits such as hair color, body type, and age rather than service quality. Furthermore, the practice can be discriminatory; Lynn suggests that if tipping practices adversely impact protected classes, they could theoretically face legal challenges under existing anti-discrimination frameworks.

The institutionalization of tipping in the United States was significantly accelerated by Prohibition in 1919. As restaurants and hotels lost revenue from alcohol sales, they embraced tips as a way to supplement employee wages without increasing their own costs. Today, the practice remains complex, with digital payment systems and evolving norms driving expectations for higher and more frequent tips. While some economists argue that tipping allows for risk-sharing in transactions of uncertain quality, the inherent social awkwardness and the inconsistency of applying percentage-based rewards to different service types continue to fuel debate over its future.
