It has nothing to do with San Francisco. It's a generational thing that has nothing to do with SF specifically. Read this article from last year in the NYT: https://www.nytimes.com/2017/07/07/opinion/the-golden-age-of-bailing.html https://www.nytimes.com/2017/07/07/opinion/the-golden-age-of... FWIW, I'm an old person and flaking wasn't as prevalent pre-cell phone. The reason is that there was no way that you could get in touch with someone if you changed your mind or if something came up, so the person would be waiting there indefinitely. Also people would have much longer patience, I would sometimes have to wait up to 1 hour for my friends to show up. Of course, the reverse of that is if someone flaked more than a couple of times, you would stop inviting them out or making plans with them, so it was a problem that dealt with itself.
