There are now two individual businesses that also act as social centers.
This became evident to me earlier this year when the San Francisco Castro district was denied a permit for a new Trader Joe’s. The Castro district reached its peak as a gay social center about four or five years ago. It could have regained that importance with a local Trader Joe's. The reason is straightforward. The Castro district lost many gay residents as they moved to other areas of the city for lower rents and other conveniences. These emigrants would have returned on a regular basis and supported other local businesses had there been a Trader Joe's.
The same is true for the Apple stores. These are social centers and magnets for any neighborhood. Walk past an Apple Store at any hour of the day.... look at the crowd. The Apple Store is a community center and people find ways and reasons to visit it.
From clusters of stores, shopping centers, being social centers we now have individual stores as social center's.
