Every day, workers in Oceania receive salary twice, once in the noon and once in the afternoon. Usually, the afternoon salary is dramatically higher than the noon one while the noon one is astonishingly higher than yesterday’s afternoon one. After getting the money, people rush out their offices seeking for foods and other necessaries. In fact, they have a 2-hour rest after each salary payment merely for this purpose.
