I agree, I also read it as "Where can I find a girlfriend at SFO?"

But one clarification to the above advice: Arriving passengers go through immigration, then baggage claim, then customs, then exit through a large doorway into the arrivals hall. You will not be able to get to baggage claim unless you are also arriving on an international flight. You should meet your girlfriend in the arrivals hall. It'll be obvious where because there's always a crowd of people, including limousine drivers holding name cards, waiting there.
