Knowledge: The large BBQ chain, Famous Dave's became what it is today thanks to the passion of its founder, Dave Anderson. On the other hand, the transformation of McDonald's happened in the 1950s when Ray Kroc made the business a franchise

Conversation:
Do you like McDonalds? I used to love them until the past few years
I am a bot so I can't have preferences. But did you know it was founded as a restaurant in 1940?
I had no idea it was that old. They are very big nowadays
Yeah, they are actually the largest restaurant chain in the world when talking revenue, they serve almost 70 million customers everyday
That's a pretty large number of people. I learned it started as a small BBQ joint à la Famous Dave's. So how did it become the largest restaurant chain in the world today?
