I've got to say that after flying for around 30 years I'm not surprised at what happened.
A few of you might remember the take off towels incident a number of years ago when the 21 crew was asked if they would give towels out when a semi official dispute was going on regarding take off towels.Management cornered the last crew to leave Sydney on a Friday night if memory serves me correctly.
Those in the office normally have an inflated opinion of their importance and do not handle jokes regarding their position with any humility.I don't know what the joke was or who it was directed at but this is not the first time something like this has happened and it won't be the last.
The part that I would like to know is who let them know about the joke.Was it a visitor lurking around the briefing rooms or was it one of the crew in the actual room.With all the glass it would be hard for someone to lurk close enough to hear and maybe it was someone on the crew..
