Well as a current F/O I've flown with almost all the female 767 Captains we have (I think bar one). This is quite a shock, as those I've flown with have been nothing but totally professional, and I might add a darn sight more pleasant to fly with than several blokes I've had to tolerate over the years.
I've also flown with a large variety of cabin crew, including on one occasion where a complaint (totally unrelated to alcohol - it was a "personality" issue - I think he lost his somewhere along the way to getting his command) about the Captain was passed through to me, managed very professionally by the crew, and ended up not causing any undue distress nor any impact on safety at all.
So I'm going to give everyone involved here plenty of leeway until the large number of blanks are properly filled in and we really know what transpired.
