Because the coffee you get at Starbucks is not the kind of coffee you can find at a typical bar and that we use to drink for breakfast or after lunch. It's a completely different market.

McDonald's doesn't have a local equivalent (it used to exist, and they got bought up by McDonald's[0]) so it doesn't have the same local (and better) competition that Domino's has, especially on a dish Italian people feel strongly about.

So basically, three completely different situations.
