3. Tip top
Within the current tipping convention, Philadelphians get the prize; customers in the City of Brotherly Love tip an average of 20.3%. Restaurant patrons in Denver and Washington, D.C., are close behind at 19.5% and 19.2%, respectively, more than a point above the national average tip of 18.1%. Some full-service operators are raising menu prices to build in a tip or service charge, a move that 43% of respondents support. But 33% “hate” the no-tipping trend, with diners in New Orleans most opposed to it (42%), followed by those in Miami and Charleston, S.C. (both 40%).
