American tipping culture has its origins in the post-Civil-War south:
> Following the Civil War and the abolition of slavery, formerly enslaved Black workers were often relegated to service jobs (e.g., food service workers and railroad porters). However, instead of paying Black workers any wage at all, employers suggested that guests offer Black workers a small tip for their services. Thus, the use of tipping to pay a worker’s base wage, instead of as a bonus on top of employer-paid wages, became an increasingly common practice for service sector employment. In the early 20th century, these employers, who shared a common goal of keeping labor costs down and preventing worker organizing, formed the National Restaurant Association (NRA). Over the past century, the NRA has lobbied Congress to achieve these goals, first by excluding tipped occupations from minimum wage protections entirely, and later by establishing permanent subminimum wages for tipped workers (One Fair Wage 2021).
