MrHorgy, Trust me - we aren't all as bad as the individual who displayed a less than professional attitude to the job at Aberdeen. There are about twenty-five of us valid on tower and, after reading your recollection of events, I am pretty certain on who it was. More importantly, I think that he will recognise himself on PPRUNE and hopefully be shamed into modifying his attitude.
There is NO EXCUSE for lecturing, bollocking, being sarcastic or shouting at pilots on the R/T, no matter how experienced or otherwise that pilot is. All that achieves is to display to others on frequency what an insecure/poor controller you are. It can also be detrimental to safety, by distracting pilots and breaking their concentration.
I would encourage any pilot to phone in and discuss poor ATCO behaviour with the Watch Manager/Supervisor as it provides valuable "ammunition" to help address that behaviour.
