Which is why the super size is gone.  McDonald's forced their employees to ask if you wanted to super size it, at hardly any notable increase to cost.  That part alone is what really fucked McDonald's over PR wise and led to them getting rid of that size.

That and their subsequent changing of ingredients in 2018.  That video of the big Mac never growing mold over the course of months probably wouldn't happen today, as they removed all those preservatives from their food.

I'm not a fan of how Spurlock went about shit, but I also can't deny he did America a favor.  McDonald's has done a shift in their food quality, with healthier menu options ever since.

I think it’s the other way around. There was a massive social movement toward healthier food options and he rode that wave, which also pushed McDonald’s into changing things. He may have helped, I guess. 

McDonald’s claims it was menu simplification.
