News of the closure stunned the clusters of customers who stopped by for their morning caffeine and favorite baked goods.

An interesting passage that may explain why it closed all of a sudden:

Hours later, Koski and a group of former Common Ground employees said in a statement they were given less than 12 hours notice about the closure, and blasted Krupp, who “was not transparent with his staff.”

They added that they had spent the previous few months forming a workers’ union, and, according to the statement, they are exploring “the possibility of forming a worker-owned cooperative to save our jobs and Common Ground.”
