Together with food costs, labor expenses are considered prime costs. Industry analysts believe that for an establishment to be successful, the combined total should amount to no more than 65 percent of sales, even though the food/labor mix may differ depending on the type of establishment. In this regard, Outback comes in at 62 percent while 21 reports prime costs at only 53 percent. Nonprime costs include advertiesing/promotion, communications expense, music/entertainmen, utillties, repairs and maintenance, and capital costs. When labor and food costs rise this usually reflects stronger economic conditions; hence sales and usually prices also increase, enabling profit margins to be maintained. In the full service sector, which would include chains like Outback and Applebee's, and the limited-service chains like McDonald's and Kentucky Fried Chicken, the cost structures resemble the breakdown shown in Table 11.2.
