So far things generally seem to be pretty good in terms of atmosphere and crew relations. Most of the (limited) whingeing that goes on centres on rosters, as you may have guessed, but in fairness it tends to be a vocal minority. Most of the others just get on with the job at hand.
BHD and SOU both have a really good vibe about them, crews are friendly and the atmosphere relaxed. You could certainly do a whole lot worse.
