I've never lived/worked in SF, but I had pretty much the same thought. Living in NYC, 9.7 miles is an almost unfathomable distance.

When Citibank built the tower in LIC, I'm sure there were people that weren't happy, but I doubt they lost many employees. That's about 7 miles driving distance from wall street.

Also strongly depends if "Daly City" was "Daly City three minutes walk from BART" or "Daly City in an office park by a freeway somewhere"

Which is practically all of Daly City.
