It's not just San Francisco with the waiting. When I lived in D.C. I waited 2 1/2 hours for a restaurant at the behest of my then girlfriend.
BTW, I don't believe that folks in San Francisco are more smug, etc than any other big city. I love it here. Don't move here, if (a) you want things cheap; (b) you want a ton of space; (c) you can't tolerate people leading "unconventional lives" (if if that unconventionality is not that radical or dissimilar to other members in the city). I love that I walk near my apartment that there are drag queens and naked people. I don't do those things myself, but I want to live in a place where you're free to do so.
Move here because you don't like the heat, you like burritos, you like to dress up in costume for no particular reason, people have the energy and knowledge to make things (new business, new styles), if you want to walk up really large hills, and if you like dogs more than children.
I've lived all over this great big nation (Chicago, Columbus, Seattle, Los Angeles, Orlando, Washington, DC, and now SF). I've visited about 43 states. For my money (and you do have to spend a lot of it) I love San Francisco.
