There's no grocery store, or bar, but Bushnell NE (population 124) does have its own independent bookstore. The Sisters Grimm operates out of a converted 1940s horse barn--notice the thick half-doors on both sides. To locals they are a "third place" coffee house, Post Office, art gallery and antique store (open seasonally). They're on the Internet too:
