Nothing Too Crazy
When I was a passenger on a rather small plane, I saw the flight attendant knock on the door to the cockpit. The captain came out, and the flight attendant went in and closed the door. The captain stood by the door for about 10 to 15 minutes, mingled with passengers, etc., then picked up some little phone looking thing and talked into it. Out comes the flight attendant, hair all messed up and adjusting her outfit. The cockpit was so tiny I can’t imagine anything too crazy went on.
