Just want to give a nod to Crop To Cuisine,\ which I only recently became aware of. A good site for food news, such as this apparent example of fast-food rage. 

I say "apparent" because the case hasn't been adjudicated, even though the subject has been indicted, which begins to lend credence. A few years ago, there was an urban legend about a crazed Chalupa customer committing violence at a Taco Bell drive-thru, but if I recall, it turned out to be promotion-fueled buillshit.

This story holds that a woman who wanted McNuggets was told they were serving only breakfast and she smashed the drive-thru window. I can imagine its being true. For a food addict such as myself, the drive-up window was an anonymous, instant-hit device, and when I needed the hit, I didn't want any crap from anyone. 

I never smashed a window, but I'm sure I was rude many times, and the idea of violence was never far from my processed-food-fueled emotional instability. (I don't blame the food for the instability, but it certainly greased its expressions.)
