S.C. Code Ann. § 59-63-720

School lunch supervisors shall be employed on a county basis, with one supervisor for each county of the State. In the larger counties of the State, where the number of school children and the area involved warrant, the State Department of Education may divide such counties into two districts and provide a supervisor for each district. In such cases the counties shall pay one half of the cost of the salaries and expenses of such additional supervisors.
