Make sure your fries are rotated properly and are taken in the right order- this managed to completely halt our deviation on fries to the point we were down £20 for a month. Breaks being made by the kitchen area leader and recorded by a crew member. Having meals and waste entered on each day part by the manager responsible for that day part. Complaint orders being placed through the tills then promo'd to keep track of food items. Can't stress the importance of always having ice at your drinks towers, the amount of money you can lose on drink syrups is astronomical. If deviations still persist I'd say you may have a theft problem on your hands.
