The last time I was in the SF apple store, the "geniuses" we're too busy chatting to one another to help me. I had to loudly exclaim "is anyone here actually working" to get them to stop talking and give me service. I have had to chase them down in the past as well.
I have only had one good experience at the apple store which was in the valley fair mall in San jose. The SF store has always been fairly bad.
I hate buying anything at Apple stores. Maybe it works for some demographic besides me, but I find it to be more work to actually purchase an item there than in any other store.
I had two experiences at Apple Stores, both have been fairly good
In one of them I managed to get good service even when the store was crowded (like Florida Mall crowded between xmas and new year). You use the iPad in the tables to join a queue, it may take some time, still it works.
