It is sometimes said that McDonalds business model is not in selling burgers but rather being in real estate. They rent out a building and a model for using it, with the goal to rent out more buildings. I don't know how true it is but I have heard that McDonalds as a company don't earn money from any profits from burgers, only from rent. Would be interesting to know how true that is.
