Thanks for the input chaps.
I am alarmed that an ATCO would automatically respond with a comment of '...bitchy comment...'. If an ATCO feels that the relationship between Pilots and ATCOs is similar to a 'them against us' routine, I suspect that particular ATCO has issues and should seek professional help. All the ATCO’s I have met around the world are brilliant people and I am sure the view expressed within this threat is not a majority opinion.
Thanks to those who have confirmed 'the way things should be', you are too kind!
Do ATC have C.R.M. or similar as a matter of interest?
