Ok all, maybe I should have said that I'm not an approach controller (although I did say intermediate levels), i'm more bothered about you lot who fly at 250kts during the descent from crusing level to FL150-ish without telling me.
I accept that safety has to come first, and in that context its not very safe to not tell me your 747 is flying at 250kts when I'm expecting it to be doing 310kts, so that the RJ100 behind you thats flying at the normal 290kts gets a nice view of your rear end.
