When I worked at mcdonalds (when i was 16) the rule was an hour I think. We threw a LOT away. It was a shame.
Youre bitching about how unfresh they are. The things are frozen and thrown into a bag and into a big box. When you open the box theyre all frozen together so you have to smack them around to break them free. Theyre probably months old by the time they get put into the oven. I just cant see why this would bother you
4 hours isnt anything since theyre kept hot in a holding oven.
