In the Far Rockaway neighborhood of Queens on a slate gray Friday in February, the food pantry at St. Gertrude the Great was devoid of clients. The woman working there, who wanted to be identified only as Marbe, explained why.”There’s nobody today because it’s the beginning of the month,” she said. People had just received their unemployment checks and food stamp benefits. “By the middle of the month, there’ll be more.”Marbe began working at the pantry in 2000 and says she saw demand spike in 2001, only to subside as more pantries opened up in the area.
