Sometimes when I'm on a plane, the in-flight meals are really quite delicious and I might want to try the other set that I did not choose (or have more of the same!). I have asked if there was extra meal kits left over a couple of times, much later when it was time for a snack ... and was informed they were all out.
Now, it seems based on Can I accidentally miss the in-flight food? that perhaps this isn't just a matter of demand, but regulations forcing the crew to dispose of heated food.
If I want to convey that I might like to try another course but without coming across as a selfish pig, and I only want it after everyone else is served, not disturbing crew too much - how would I go about asking for it?
