A totally irrelevant post. As most readers will know, on SOME layovers, some of the crew come out. On SOME layovers, none of the crew come out. On SOME layovers no one goes out and on SOME layovers none of the flight deck go out.
Maybe on your particular flight, the flight deck were very tired having had tough rosters, or maybe they did not actually want to spend any time with you. After all, the maturity displayed from your last post would surely keep even the most childish of pilots away.
Or probably more realistically, there weren't any great looking girls...
Now how's that for honesty?
