About Super Size Me:

Super Size Me didn’t have a negative effect. We actually have a theory that it helped us. Any publicity is good publicity. Too much of anything is bad. A lot of the guys here watched it and thought “Yeah but why would you eat McDonald’s for every meal, every day?”.

and how much does it cost to make that dollar cheeseburger:

It changes based on many different variables but something like a double cheeseburger usually produces a LOSS of 10-30% we call it a loss leader. We want you to come in for a double cheeseburger, see the menu and buy more than you expected. A soda (600-1000% profit margin) can easily make up for the loss leader.

plus lot other gems like these.
