Re the SYD service I have always found the Accor staff quite indifferent (in both lounges). Certainly not what I would expect. ...
This has been my disappointing experience in the SYD Flounge. Last time I arrived with enough time for a leisurely meal. I left without eating anything: could not get seated (despite space available), could not get menu, could not get drinks, could not get order taken; could not get served. In the end i asked for some ice-cream: even that came so late I did not get to eat it.
I do not doubt the veracity of the OP but (perhaps fortunately) I have not had a bad experience in MEL FLounge
