Roy Rogers Restaurants is a subsidiary of Marriott Corp. which sells franchises to own and operate standardized fast food restaurants. Many franchise owners operate more than one restaurant. One of these, presently operating 16 restaurants and committed to develop 30 more by 1992, has asked to remove the salad bar from some of his restaurants. The salad bar is a unique feature required by Roy's franchise agreement, and allowing its removal threatens standardization of the chain.
