Some cabin crew have strange ideas. Recall some years ago an SV TriStar landed Cairo and while taxiing to the parking bay experienced an engine rundown/tailpipe fire on number one engine. The cabin crew noticed this, and tried to evac...out the PORT side. The Captain was able to stop the aircraft...and stop the evac only because the L3 door would not open. Quick communication from the flight deck prevented a very unpleasant situation.
