Does it actually matter? It seems that no matter what flight I take in Y, SFO-HKG or HKG-SFO, regardless of direction, or the time of day, dinner shows up first, followed by a little ice cream, then a sandwich half way through the flight, and then breakfast before landing.
What I want to know is what happens to the food when I almost never eat it anyway? That is I decline the service. Does it re-appear in the next flight for some lucky passenger?
