In the olden AN airline days, I took an SQ reward flight, ADL - SIN, and when the SQ FA came to ask what I wanted for a main lunch, she came to the level of me seated (which I didn't expect, like knelt, respectful sort of thing, it was my first Wow SQ moment), ... compared to QF J when I fly JC (Jetconnect), the FA/CSM stood (while saying my name from manifest), asking what I wanted.
EK was the best one wine wise, always coming by with the caraffe on that 4 carrier server, ... asking if I wanted more "grog".
EK crew (FA) tend to be from Thailand, or those from the EU countries region, and SQ crew, they are probably taught or ingrained to serve their flyers very well.
Probably QF and JC and JQ, bear/bare minumum will be acceptable.
SQ/EK crew will never say, your meal wasn't loaded! Am sure they wouldn't admit it, probably use another reason, but would not be as gruff as "your meal wasn't loaded!".
