On Fridays at Jerusalem‘s Mahane Yehuda market, about an hour before Shabbat begins, merchants begin to close their stalls while a group of some 20 people gather with bags and baby strollers, ready to rummage through fruits and vegetables left in cartons and pick up produce left on the floor. Most are elderly, some even very old, but a number of young people with ashamed looks on their faces are also among the group.
