In June I flew BNE - SIN in J and was asked if I wanted meal service shortly after take off or before arrival which I chose as I wanted to get to sleep ASAP.
I would expect this to also be asked on SQ 218
I think it might of been a tip I picked up on here, but I have found not eating after take off allows me to sleep better and not be as tired the following day on over night flights.
In November I flew SQ 218 in Y and I can not remember if it was this flight or the returning SQ227, but I recall not noticing any meal service at all, though think it was SQ218.
I most likely went to sleep before it and the cabin lighting was raised 20 minutes or so before landing.
