Parapunter....
I am not in aviation catering, and when you talk about 5 grams of this and 20 grams of that and 15 grams of the other, I can't exactly visualise this on the tray in front of me, but I do know one thing....in every business cost control is King otherwise you will be out of business soon. It does not mean that what you produce, whether it is widgets or white sausage is of poor quality. Simply that costs are controlled. Is that too simplistic.??
I well remember the BEA days (Ahhhhhhhhh de Haviland) when the difference between a First Class Breakfast and a Tourist one (Coach to you) was one Banger.! How things have changed.
