Watching The Founder about Ray Kroc stealing and cheating the McDonald's brothers out of their McDonald's creation https://www.amazon.com/Founder-Michael-Keaton/dp/B01MY7FSMF

The brothers agree to a $2.7 million lump sum payment, ownership of their original restaurant in San Bernardino and a 1% annual royalty but when the time comes to finalize the agreement, Kroc refuses to include the royalty in the settlement and instead offers it as a handshake deal.

The McDonald brothers were never paid their royalties, which would eventually have been about $100 million a year


I am sure them McDonald's burgers in 1954 tasted a whole lot better than they do now.
