Fresh story this time. One day we had these prepackaged Smuckers brand "grilled cheese sandwiches" for lunch. They were a new addition to the school lunch menu so most of the kids grabbed one. Once you open the hot paper sleeve, however, we all found that our "grilled cheese" was actually just a processed wheat pocket that had been puffed up with air and good ol american cheese. As soon as you bite into it, the other side of the pocket would burst open and release a foul-smelling odor, as well as draining all of the liquid "cheese" which looked more like poorly mixed viscous vegetable oil. It was awful. What's worse, most of the kids actually ate it. And most of those kids ended up running to the trash cans in the middle of the cafeteria and barfing in them. It looked like the beginning of the Hunger Games where everyone runs to the middle. The nurse's office was packed beyond max capacity and school was cancelled for the rest of the day. All that I can remember clearly was the sour stench in the cafeteria. It scraped at your throat and made you want to puke along with them. Edit: added a pic for a more immersive experience.
