crew "scoff the leftovers"???? As a very frequent flyer, I am totally "off" most airline and lounge food, even though I travel in the pointy end and get all the great lounges. And as much as I fly, I still don't suffer anywhere near what the crew face, they live/work surrounded by that reality. I am sorry, but a perception that crew would not only wish to ingest that stuff, but "scoff" it, is insane.
Forgive my reaction to your post, but I love the english language, and a term such as "scoff" implies something akin to greedy swine excessively gobbling up some divine morsels.
Absolute rubbish.
