Larry David is adamant about the unwritten rule of appetizer allotment. In this scene, Richard Lewis is also eating “too much” of the hummus that they have ordered to share. The “unwritten rule” is that the dish should be split evenly among the diners, but there is a strong personal incentive to eat more than your share. In a sense, this is similar to the tragedy of the commons. While it’s in the best interest of the group to split the resource fairly, some people may try to take advantage of the situation.
