In other words; if you're bad at your job, you probably won't have it for very long. Yeah, well no crap.
One must question why a subset of the food service industry should be treated so differently than any other. Is the McDonalds restaurant worker (who gets no tip) just doing so well that they don't deserve the same consideration from the public as someone working in a ramen shop? Or does that employee face a different commute and living situation? The delineation is strange.
>If you accept the notion that you get tipped less because you are a poor job performer, what is the point of laws that force employers to make up your wages to minimum wage?
The point would be to... establish a _minimum_ wage, regardless of performance. What about that is confusing?
