Agreed...here's why - back end of my career I stupidly thought we had resolved a problem down route to everybody's satisfaction.
The number of occasions down route either myself (or the Captain) had to sort out crew trouble, usually alcohol related were so numerous that they were getting reputations at certain bars and a few were banned (!) - some individuals were notorious for trouble... the usual suspects. We were forced to leave one girl behind in Tbilisi after she fell "ill" (aka drunk at 0500) when reporting - there are a few things I don't miss.
