One of my coworkers did this. The bag ignited and was burning in the microwave. Smoke poured out and the whole office stunk. I can't believe the alarms did not go off. We opened all the windows, set up fans etc. but the smell would not go away. We inhaled so much smoke I felt like I smoked a pack of cigarettes. I feel for you, we wanted to banish this woman from the office! She kept walking around all day sheepishly saying, "I'm sooooorrrrrryy."
But to see if the rest of my office was afflicted with the same selective amnesia, I just yelled from my desk that I felt like eating popcorn. 
The loud, resounding "NO!" from the collective office tells me that their memories are intact. The fact that they are all talking to me tells me that they understand that mistakes happen and that even this pretty bad one doesn't make me the office idiot....RIGHT?!?! 
We get a few BAD popcorn makers but the worse was some guy who melted out the entire microwave overnight by setting his dinner for 60 MINUTES!! He said he FORGOT ABOUT IT!
