Men, Republicans, and northeasterners are the best tippers. Women tip a median of 16 percent, while Democrats and southerners leave a median 15 percent at a restaurant, according to a new survey of more than 1,000 American adults. That's compared with the median 20 percent left by men, Republicans, and residents of the northeast. Those who pay with plastic leave a median 20 percent, compared with 15 percent for those who pay in cash. |
