McDonald's franchises are required to follow the directions of the parent company and perhaps more than a few have complained about the Forever Young changes. First, customers needed to recognize the mansard buildings and identify McDonald's with them—a new look may initially generate some degree of confusion. The next objection is cost: as of 2008, a newly built swish-brow store was said to cost upwards of $1 million and renovation of an existing unit to meet the new standards as much as $400,000. With a large percentage of sales from drive-in business, franchises could argue that the expensive interior redesign is unwarranted for their bottom lines.
