Like most things in New York, the Park Slope Food Coop is exclusive, filled with beautiful people, and a source of high drama in the lives of everyone involved with it. Most everyone I know in Brooklyn is a member, and all of them are on some sort of weird coop probation because they're behind on their shifts. Skipping shifts is really naughty, and the lengths to which some members will go to get out of them has become the stuff of folklore. On the other hand, others seem almost pathologically conscientious — in a recent issue of the newsletter was a story of a member who had written into the coop to explain his absence. You see, he was in prison for eco-terrorism. So he may not, you know, be able to cover that Tuesday afternoon produce sorting shift.
