Wrong on so many levels, yet I laughed heartily and you will too. We’re all going to hell together

Someone took a picture in the back of a McDonald’s of a sign posted supposedly denoting how much the actual ingredients cost. I’m assuming these are prices per container? Can’t imagine how mayo would cost so much more than meat. Any explanations?

You’d think the answer to the question is obvious, but sadly some people may never be able to grasp the logic.
