I have not visit HK for >15 years until I returned in 2006 to change my HK ID card to the smart ID card. From the moment I landed I was very surprised and impressed how kind the immigration officials are in the airport. When I went to do the ID card, they were very polite and helped me for anything I was uncertain of, and making sure I was happy with the photo taken for the ID card.
This was not the case in the past. I was expecting a lot worse.
So, well done to HK and it made me very happy to see my fellow HK citizens.
I have visited HK for a few more times since then and each time I have happy memories when I buy things. Even the cheapest HK style cafe they are very polite outside the tourist area.
