> Without tipping far too many would take your money for granted and the quality of service would decline across the board because there is zero incentive to provide anything better.

I don't mean to sound flippant but, have you ever been to Europe? I've traveled to Germany, Ireland, Finland, and Iceland multiple times. None of those countries has a tipping culture and the service I receive, even at your basic fast food restaurant, is the same or better than in the States.

I must ask, why do you believe your statement to be true?
