You’re right, of course. But I think what’s happening with tipping is that many people see that a minimum wage is absolute crap to live off of, and so it goes up. (“Minimum wage for minimum skill!” others cry. Again, even if you believe that argument, it’s still not keeping up with inflation, so it’s worth less now than then.)
I said this earlier (I think), but I would prefer to deal away with the whole tipping structure and just have wages rolled into my meals. The way it’s set up now, it’s just a system of those who tip less taking advantage of those who tip more to make up for them, and meanwhile minorities get caught being undervalued. Example: a Cornell study found that at one restaurant in the south, white servers were tipped more than black servers. A follow-up study in the Midwest showed the same thing. White servers as a whole are tipped more than minority servers. Part of this could be where they work and their access to higher-end which is a whole host of other problems. And then there are servers’ attitudes to customers. A Wayne State survey suggests that a number of servers have discriminated against black customers or have seen co-workers profile customers because they didn’t think they’d get tipped as well. Three Missouri Applebee’s employees were fired over racial profiling, and eventually the restaurant closed. We may want to think that the days of racism and sexism are behind us, but they’re not, and the world of tipping is affected by it.
