You know many lower income people who are commuting long distances into the city? Really?

Sure, many come from Oakland. Which was the point of the article.

And when I was still in school and knew a lot of people in these types of jobs, many worked two (or more, if part time). And still couldn't really make rent. This is why I never tip below 20% unless the server didn't do their job very well. It's expensive to live here and they have a tough situation.

Also, Bus Drivers don't belong on that list. They are certainly paid more than wait staff, etc.
