taurant tips are generally not expected.
In India and Africa, where the gap be
tween the prosperous middle class and the
poor is often huge, tips are most certainly
expected. Some academics have tried to
see whether a stronger tipping culture cor
relates to measurable psychological traits
in different cultural settings. One study
across 30 countries suggested that tipping
was more common in societies where in
equality was rife and where the guilty feel
ings of the welloff are more acute. In some
settings the onus is plainly on the custom
ers to be more generous, thanks to an on
line ratings system whereby they are
judged by the server. For instance in Doha,
the Qatari capital, users of ridehailing
apps fear that without providing a cash tip
their customer rating will fall, making it
harder for them to catch a cab in future.
The most obvious economic justifica
tion for tipping is that it encourages the
server to perform better. But the logic of
the tip as an incentive is far from solid.
Most customers in restaurants are not reg
ulars. A onetime customer will not benefit
in future by leaving a tip at the end of a
meal. But even repeat customers do not
seem to use tip rates to reward or to punish
the server. Mr Azar says that if they did,
their tips would more closely rise or fall ac
cording to the quality of service than with
more casual diners. But he could find no
such evidence. More strikingly, service
quality in countries such as Japan and
South Korea, where tipping is exceedingly
rare, is not noticeably inferior to service in
America or Europe.
If tips operated as incentives, one might
expect them to be more common in profes
sions where the customer repeatedly inter
acts with the provider. But that does not
seem to be the case either, since a wealth of
professions, such as dental hygienists, car
mechanics or vets, entirely lack a culture
of tipping. In Mr Azar’s survey, only 14% of
Americans said they tipped to avoid poor
service in future.
One study finds that quality of service
explains a variation of no more than 5% in
the size of the tip. In a study of rides using
Uber, where only 15% of trips are tipped,
the passenger’s characteristics proved
three times more relevant than those of the
driver when explaining the size of the tip. A boss’s scam?
Tipping quite often benefits the restaura
teur or business as much as—sometimes
even more than—the recipient of the tip.
Having enticed a customer with low up
front prices, a tip is then extracted later—
and sometimes doesn’t even go entirely to
the supposed recipient. Recently online
platforms like Twitter, Facebook and You
Tube have sought to keep the best talent on
their own platforms by letting their star
“creators” accept tips, with the companysometimeskeepinga sliceforitself.Order
