If you're a server and your customer is a Republican man in his 50s with an Amex card, you may have hit the jackpot.
That is the profile that a survey by CreditCard.com generated to describe the best tipper in America.
The site found that men, Republicans, Northeasterners and Midwesterners, baby-boomers and credit-card holders leave median tips of 20 percent at sit-down restaurants.
Women, meanwhile, average around a 16 percent tip, while Southerners are the worst tippers geographically with a 15 percent median. Democrats, typically, also tip around 15 percent on average.
It also found that people who pay by credit card are more likely to tip a higher percentage than those paying by cash, with 91 percent of credit card users saying they always tip wait staff, compared to 76 percent of cash users.
The findings come from a poll of more than 1,000 people in June, and highlights age, sex, geographical and political divides when it comes to tipping.
GoMN's Tip Jar column has this guide on when and how much you should tip.
So what about Minnesota?
Well like we noted above, Midwesterners are among the most generous tippers in the nation at 20 percent – a figure that we can only assume was achieved thanks to a big dollop of Minnesota Nice.
They're not as generous when it comes to tipping for haircuts however, with just 11 percent of Midwesterners tipping their hair stylist.
But they are among the most generous at the coffee shop. Though tipping etiquette is a bit more of a gray area when it comes to baristas, more than half of Midwesterners say they drop some cash into a coffee shop tip jar "always or most of the time."
Weirdly, people who earn more money are less likely to leave tips in coffee shops, with 55 percent of those earning $30,000-$50,000 saying they leave tips, compared to just 41 percent of those making more than $75,000.
The survey also found that Republicans and Independents will tip more than Democrats. Fifty-nine percent of Republicans and 57 percent of Independents say they tip more than 15 percent. Only 46 percent of Democrats do the same.
