I see your point. However, if I may report an exception (yes, the only exception I have experience so far) to this - QF81 SYD-SIN in Mar/Apr2022. There was this CSM, who welcomed me as WP. I was flying Y, seat 24C. Kept checking on me every couple of hours or so, refilled my G&T without asking, meals served first before anyone else in the cabin, excellent and attentive service. As we were about to land, came to my seat once again, thanked me for flying with QF etc. I got off the plane, wanted to check the QF F lounge and it was not open yet. So as I was walking back to QF J lounge, the same CSM was walking out of SIN with his crew. He stopped and enquired if I needed any help. I told him that I was checking if the F lounge was open, it was not and I was on my way to J lounge. He then told me how to get to the J lounge and had a chat re where I was headed to next etc.
