Men and people living in New England are likely to pay the biggest tips to babysitters, whereas drinkers in the mid-and south-Atlantic states give the most love to their bartenders.
Gen Y customers, households in the Mountain states and those making either between $50,000 and $75,000 or more than $100,000 tip food delivery guys a median of more than 14% on their tabs. That's well above the 10.3% national median reported.
In most parts of the country, salon workers typically get tips in the 15% range, but pull in more than 17% in Mountain states and close to 20% in New England.
Those making more than $200,000 reported paying somewhat higher median tips than other income groups for babysitters, baristas, bartenders, food delivery drivers and salon workers.
Of course, none of the workers in these jobs are taking home huge paychecks, so they rely on the tips they receive to make ends meet.
In a separate PayScale.com survey, taxi drivers reported that their median tips account for about 25% of their income, on top of their median hourly base pay of $9.90. Waiters and waitresses are not even required to be paid minimum wage. They reported a median hourly base of $4.40 and said their median tips accounted for more than 62% of their income.
