vintage... many years ago I was a Flight Data Officer (assistant) to a group of Procedural controllers working a Flight Progress Board (cardboard strips). One of our lady controllers was working Sector 3 (northern third of Western Australia plus ocean to the boundary of Bali and Jakarta FIR's). I remember one time when she was trying to co-ordinate with Bali and the Balinese controller couldn't understand what she was saying. So, instead of rewording it a different way or simplifying it, she started yelling exactly the same thing in a louder voice! She said the same thing over and over again, louder and louder, until finally she gave up in frustration and de-selected the satellite line.
She had a really high pitched voice and at one stage she was shrieking. Every controller in the centre had turned around to watch...
