CHAPTER 5 Operating Practices and Policies OFFICIAL COUNTY POLICIES should include credit terms, approval of vendors, time of call, delivery time and place, and other services available. It is recommended that all school lunch departments have a well-organized plan of buying. Foods should be purchased wholesale if possible, and all purchases should be based upon the best available price, quality, and service. Tax Exemption The Florida Revenue Act exempts schools from paying state sales taxes. A sales tax exemption certificate is issued to schools on application to the Comptroller's Office, Tallahas- see, Florida. It must be presented to the dealer when tax- exempt purchases are made. Procedure For Checking In Supplies All deliveries should be checked on arrival for weight, quantity, and quality and signed in by the school lunch man- ager or an employee designated to perform this function. Properly itemized invoices should accompany the delivery and be placed in a properly designated file. Carrying Food From The School Lunch Premises The school lunch department should not be used to make any purchases other than those goods for use in the school lunch program. This policy, for example, would prevent: 1. The purchase of a ham, a loaf of bread, or a case of canned goods by any school-associated individual for home or other consumption
