On the face of it, McDonald's corp should also be harmed by this. It makes their customers less successful through higher costs & lower sales, and it tarnishes their brand when a customer of their customers is unable to purchase an ice cream.

The two questions in my mind after watching:

1. What makes McDonald's corp okay with it?

2. What is the difference between the arrangement with McDonald's and the other franchises/chains? (Wendy's, In'n'Out, etc.)
