Tipping compensates some workers substantially more than others even when the services they provide are comparable. Knowing who gets the biggest (and smallest) tips would benefit workers, businesses, and consumers alike, so this chapter looks at how average tip percentages co-vary with the recipients’ sexes, ages, races, physical appearances, work-experiences, work attitudes, and personalities. Although there are meaningful effects of server demographics and appearance, the data suggest that no server characteristic is really critical to getting good tips. Instead, servers’ average tip percentages are determined by the unique combination of many traits that each server brings to the table.
