The strange caste. 
Companies have many ways to make money, but some large companies make money with strange and unusual methods.

Part1: McDonald’s: 

They earn more than they earn from selling hamburgers, from selling their “right points” branches. Today, McDonald’s is one of the most successful real estate companies.

Part 2 of Strange Caste:

Toyota Company: It was a time when Toyota’s sales and sales revenue was greater than its car sales. For example, MG racing cars cost more parts than their own cars.
