What's behind America's burning desire to stick with tipping at restaurants?

Many Americans don't want to let go of tipping because they see it as a step toward socialism, or because they don't want to lose the power to judge service

As progressive American municipalities roll out a $15 hourly minimum wage, one result has been a renewed debate over the practice of tipping service workers. Some restaurants are experimenting with compulsory service charges as well as other systems that they hope will ensure all employees earn more, while rewarding high-performers and still allowing the customer some say.
