Picture this: it's lunchtime and the office kitchen is crowded with people using the microwave. The smells start to aggregate. A Lean Cuisine here. Leftover lo mein there. Then, before anyone can intervene, some fool coworker commits the biggest offense of all: he or she reheats last night's trout dinner. For the rest of the day, the office smells like the deck of a fisherman's vessel on a hot day.
