CAMBRIDGE — On Monday afternoon, Marc Najarian stood by the door of his store, acting like a pallbearer at his own funeral. “Hi. Ya heard?’’ he asked his Fresh Pond Market patrons before enveloping them in his arms.

Every grocer knows his expiration dates, and Marc Najarian is no exception. So the septuagenarian and his brother Crosby were busy consoling longtime customers as news spread that their family-owned market in the Huron Village neighborhood of Cambridge would be closing this weekend.

“Oh Marc, what am I going to do, what am I going to do?’’ customer Barbara Riley wailed, tears brimming, as she embraced him by the checkout counter. “Do you still have chicken? I’m coming in twice this week.’’
