 This is the Bloomberg Black Business Beat. Derek Hayes is founder of Big Dave's Cheesesteaks, a growing chain of fast food restaurants in Atlanta serving Philadelphia-style cheesesteaks. Hayes named the company after his father to honor his legacy. My father, he got diagnosed with lung cancer in 2009. He wound up passing away, and I honor my business to him. So everything Big Dave, people say, why are you so small? And it's my father, so I take that with dignity every day.
