After getting your job, on the second day of work move all the boxes to Warehouse 3 as normal. When the shift ends, do not go to the back of Warehouse 17. Instead, play darts or practice your moves to waste time until Ryo says it is time to go home. When you wake up the next morning, you will have the same work day over again. If you made quota the previous day, you will get paid more money for the same job. This can be repeated as much as needed.
