The owners of Market Bakery, which the couple opened in 1975, and Buttercup bakery, have lost half their business since they were reclassified as a restaurant and can no longer take food stamps. On a recent morning, only a few customers bought doughnuts and cookies, and the owners lamented lost sales from four cake orders they took but were unable to fill because customers wanted to pay in food stamps. The couple has laid off five of six employees and is considering shutting down one of the two stalls.
