Long time back I was attending a NIH meeting in DC. All my colleagues went for lunch; I decided to go to my room and make popcorn. Left the popcorn in the microwave and forgot ..and there was smoke everywhere. Frantically I tried to call the front desk to assure them that there was no fire and it was popcorn burnt and smoking in the microwave-too late, guests were evacuated and my friends were not allowed to enter the building. Of course, the meeting was delayed by about 2 hours and since then my friends would suggest that I ask for a Microwave oven less room.
