However,
studies have consistently observed a reliable black-white tipping difference even after controlling for consumers’ socioeconomic status, including income and education, and after controlling for perceptions of service quality. This race difference in tipping is also observed regardless of whether the server is
white or black.

Data from a national telephone survey revealed four general patterns in the
tipping behaviors of Blacks and Whites. First, Blacks appear more likely than Whites to stiff commonly encountered service providers, but not less commonly encountered ones. Second, Blacks appear more likely than Whites to leave flat tip amounts to service providers who are commonly tipped a percentage of the bill, but not to service providers who are more rarely tipped a percentage of the bill. Third, black percentage tippers leave a smaller average percentage of the bill than white percentage tippers across many service contexts. Finally, black flat tippers leave larger average dollar tips than white flat tippers across many service contexts. The theoretical and practical implications of these findings are briefly discussed.

If there was a scale listing every demographic from best to worst, we (Blacks) would rate last, and this stereotype seems to transcend class, station, and situation. If personal anecdote is any indication, the stereotype may be rooted in truth. I’ve witnessed numerous friends, family, and colleagues leave substandard tips when both the food and the service were on point, including the time a friend with a six figure income left a
$1 tip on a $70 meal (and this Negro had the nerve to leave a smiley face next to the $1). While that’s just one (extreme) example, I’d wager that a quick survey of bartenders, waitresses, and others in the service industry would tell you that behavior is more the norm than the exception.
