I am GO and I flew to/from Hongquaio in Y with KA recently. I was greeted on the outbound as I had reserved a special meal.
On the return journey, with no special meal booked, I flew with my boss who is also GO and was sat behind me. The purser came by and said Hello to me but not to my boss! My boss is a local chinese lady so she was a bit miffed about it all! ;-P
