Its strange as well if you work the same units the mental image you have of some controllers. And i am sure they do the same with pilots.
There is a Bloke at MAN on radar and tower who has what I think is a great manner. Nothing ever seems to phase him. Very pleasant doesn't have the most correct RT but gets the job done being pleasant, with a dry sense of humour which he has no problems using on the RT. The end result that the flight crew want to help him. I imagine him as a grandad who likes nothing better than a glass of wine while the kids are opening xmas presents shrugging off bollockings from granny and daughters with "yes dear" and continuing as before spoiling the kids.
Now a female controller at BHX I imagine as a twisted old crone with fag teeth and a deep hatred of men. Who I take great pleasure being nice to because it completly knocks her off her stride being crabbie on the RT.
