I have noticed a bit of sloppiness from ATC in HKG with regards to multiple instructions issued at once, as well as altitude clearances with a frequency change. Very poor practice and will end up biting someone.
But to be fair...does HKG ATC only selectively issue multiple instructions to local airlines and those airlines that can cope...?
In which case, one might applaud the level of HKG ATC expertise and professionalism?
