A tiny bit off topic but still related.
When the aircraft smoking ban was first introduced it was common on the 747 for cabin crew smokers to remove the trollies from their stowage in the galley, which leaves a large sealed area, get in and have a crafty smoke!
Many a time I appeared in the galley and opened the doors to find a red faced steward/ess hudled up (cold as it is chilled) and surrounded by a fog of smoke.
Happy days
