He explained: You get a group of people together, with one person as the head, the organizer—for the ones he was in, it was the head chef of the restaurant where he worked. Say you have 10 people. You put the numbers one through 10 in a raffle, have everyone draw a number; each number represents a week. When your number comes up, when it’s your week, everyone pays you a set amount of money, $100, say. The other weeks, you pay $100 to the designated person. You take turns receiving the money, and when you’re not on the receiving end, you’re paying in.
