there's this company that has written in to contract w/ McDonalds that all franchises must buy this particular ice cream machine that breaks a lot but only a particular company can repair it and that company (who i think is owned by the same guy who owns the machine company) costs a lot (monopoly) and isn't timely. So essentially McDonalds get's their cut up front and the ice cream company get's theirs on the backend while the franchise owner has to choose between paying a lot in repairs or pissing off customers. And I guess McDonald's cut of the lost business from the ice cream doesn't incentivize them to step in.

So I'm sure there are a few angles that could be played by the FTC that are quite legit
