Mr. Veloo, I fully agree with your take on unnecessary announcements that jam a busy approach frequency but I do not agree with your opinion on your colleagues (some KL controllers) with regards to apology. In fact some of your peers are downright rude and issue clearances with irritated tones.
Slashing off AGOSA estimate by 3 minutes when you are 40 miles away is impossible. Getting irritated when a pilot declines it is unprofessional.
As much as I do give credit to most of your colleagues, there are a few who give good controllers like you a bad name. For instance, I heard a controller who was pressed by a pilot for the traffic that is preventing his climb to requested level to be told off to "keep quiet".
There was once where ATC who cleared 2 aircrafts on the same taxiway facing each other not uttering a word of apology.
I would like to see KL ATC at par to the least Singapore Controllers. Don't want to compare with London yet. We have a long way to go.
