The McRib sandwich couldn't save McDonald's (NYSE:MCD) this time. The fast-food giant just reported a nearly 1% dip in sales for the month of November. That follows a disappointing October, when the introduction of Mighty Wings and a new flavored coffee failed to boost revenue in the United States.

In the video below, Fool contributor Demitrios Kalogeropoulos puts the company's latest sales numbers in perspective, noting that the overall fast-food market is flat right now. He also argues that McDonald's can return to industry-leading revenue growth next year if it manages to boost customer service levels while also providing some real product innovations.
