Third-party delivery services have been a hit with customers and a successful solution for some major chains. But many restaurant operators — in particular smaller and independent restaurants — are not so happy about rising commission costs and lack of control over customer data.
The survey, conducted for CreditCards.com by GfK Custom Research North America, shows that 10 percent of millennials (ages 18-37) leave no tip for a server at a restaurant. Three percent of older diners do the same. The survey also found that men, Southerners, Westerners, parents with young children, lower earners and less-educated people tip less than the norm at restaurants.
