So my friend really wants me to come out to San Francisco this summer where she hopes to have an internship. I would really only be able to be there June until August, and won't be 21 until the end of June. Can anyone tell me what the chances of me finding a job out there for that length of time would be? It's not exactly Europe where I figure I'd have an easier time. I have no idea if I want to do this or not, but looking for some feedback! Thanks!

You could probably find a part-time job pretty easily.. One of my roommates, instead of working one full-time job, prefers to work several part-timers. A lot of places in the hip (though gritty) Mission District seem to have pretty high turnover, so I don't see why you wouldn't be able to get a job pretty easily at any of the many bars/restaurants/shops over there.

Let me know when you get here!
