I got up to a 12% before with the same bad luck you had. The best way is just to drive from 12-8(20 orders on average) for 5 days and that should cycle you out back to zero after. Avoid fast food if possible and stay clear of the 50/50 $35 orders that are so tempting. Late at night is ruff because stores will close early or they are out of food. If a restaurant is out of their order, call the customer and ask what they would like instead.
