What does slinging pizza have to do with running the country?

We have, yet again, another Republican who wants to run for president. Herman Cain was once the CEO of Godfather's Pizza. Forgive me, but how does running a chain of pizza franchises qualify him to be commander-in-chief? How does him making sure my pizza crust is fluffy and fresh while simultaneously making sure my cheese is hot and tasty enable him to effectively run the U.S. economy, the military, Afghanistan, the war on terror, and tackling the debt? Maybe if he was CEO of a top tier pizza chain like Pizza Hut or Papa John's, I might envision him as secretary of the FDA or Agriculture secretary. Can anyone please enlighten me on why making sure I have enough parmesan and red pepper packets is a desirable quality in a candidate?
