Oh boy, that's a kneejerk reaction for sure. The next time I fly SQ J, assuming that SQ still hasn't íntroduced dine on demand, then I'm going to make a point of checking with the FA as to the service timings -- and if they plan to re-time breakfast that way, then I will inform the FA not to wake me for breakfast!

Of course, in the grand scheme of things, meal timing does not compare against injuries during turbulence, but completely moving the meal service by 2-3 hours is definitely a non-starter. I imagine this would wreak havoc on their SIN-EWR and SIN-JFK "longest flights in the world" with 3 full meal services...
