Wholesale Dale is available once you unlock the business. It works very simply and requires you to sell various amounts of servings of food. The serving amount is based on the level of your cafe, eg. a lower level player will have to sell less dishes to Dale than a higher level player. This is done by clicking on an item that has been served on a counter and then clicking "SELL TO DALE!" and choosing the number of servings to sell. All servings are sold to Dale at 2/3rds of their normal sale price. Once you complete the mission you will get cafe points that also scale with your level..
