With everything else the left is incensed about these days, you could be forgiven for missing this one, but for the past few years it’s been a very trendy liberal cause to rail against tipping. I suppose this stems from the fact that customers freely choose the amounts they tip servers, and to a large extent it’s merit-based. Since the left assumes just about everyone is a seething racist, they also assume you’re making your tipping decisions not on the basis of how well you were served, but on the basis of the skin color or gender of the server or whatever.
