I read a lot of articles on HN nowadays that are part of what I think of as "SF exceptionalism" -- articles around the idea that things in SF are somehow very different than in other places. Even when couched in the form of a complaint, as this article is, it's hard not to think that what the author is actually doing is showing off about how rich their city is -- look, toast and coffee here costs $6!
I've lived in the Bay Area a long time and this sort of attitude puzzles me. There are plenty of rich areas up and down the Valley, and many places where a $6 breakfast is not something to write an article about. But yes, because it happens in SF it must be special.
