Yes on a HKG-CNS and CNS-HKG I was given bottled water in a CX plastic bag and on a YYZ-HKG the ISM came to greet me and I asked for a bottle of water and she returned herself, with a bottle wrapped up in Kitchen Towel. All 3 times the water was handed out in the most covert way possible.
I think this is the best approach, hand out water in sometype of casing/bag.
I have to say though, it is much appreciated to get these perks, as I drink a lot of water to stay hydrated in flight. On my YYZ sector I usually drink 3 bottles of water and a few cups from the FA.
