I work at a coffee shop called Starbucks.  Are familiar you with them? 
I know a bit about them, like for instance I know the company was founded in Seattle in 1971.
Who was the person that founded Starbucks? 
I'm not sure to be honest, but I know Kevin Johnson became the CEO of Starbucks as of April 2017.
Is Kevin Johnson a billionaire? 
I would say there's a good chance, he joined Microsoft in 1992 and served as an executive there, so he must have quite a bit of money from that alone.
Is Starbucks the largest coffee chain in the USA? 
I think it's probably the largest or 2nd largest, they have 23,768 locations worldwide as of November 2016!
Are they a publicly traded company or are they private? 
I believe Starbucks is a publicly traded company with a sticker of SBUX on the Nasdaq exchange.
