San Franciscans have officially lost their frigging minds.
If anyone you know must absolutely have one, here's an alternative. Send them to me with $50.
After I smack them upside the head, I'll hold a mason jar outside my house in South City and get some fresh stuff as it rolls over the hills from Pacifica. (For $75 I'll scoop it up driving on 280 from either side of the Fog Wall.) While they're sipping on their "authentic experience", I'll get online and donate to SPCA, Cat Town, refugee relief...any of a zillion organizations that can multiply $$$ for good, with the added benefit of saving folks from being douchebags. Win-win.
