Economic theories to the side, people tip for varying reasons. Some people tip to reward service. Others to impress a partner. Others will tip in order to assuage guilt. Some consumers tip, because they recall what it was like to work for tips, themselves. There are others who refuse to tip, maybe because they were never tipped or are short on money themselves. This is like an argument about trickle down vs trickle up economics with both sides thinking they are absolutely correct, when in the real world there are various forces that change the rightness of either position for different times, places and people.
