The situation at the Sony Metreon in San Francisco continues to go downhill. Even Spiderman, currently crawling down the side of the building, can’t save the day because although the movie theatres are pulling in capacity crowds, that hasn’t translated into retail store sales. The customer-relations staff has been let go and Sony may hand over the reins to a mall management firm. The Discovery Channel store is looking bare with cutbacks on inventory, MicrosoftSF left in November, and Sony isn’t looking to duplicate this facility, once considered a model for future sites elsewhere.
