There’s a crime that happens in our office almost daily. Someone—no one knows who—burns popcorn in the microwave. The smell lingers like a dark cloud over the entire floor. Every time it happens, we launch a full investigation, but the culprit is elusive, always striking during lunch breaks and vanishing without a trace. Last week, it was so bad, the fire alarm went off. We all evacuated, standing outside in the parking lot, while the building reeked of charred butter. How hard is it to press the “popcorn” button and not walk away for 10 minutes?
