i have seen many times cc going down the back with j-class meals covered with a tea towel and this is after the j-class meal has been severed
the rimless,I know what has been
severed and it wasn't the meal service.
What makes you think they were J/C meals?
As Pegasus has said what you have seen are the CREW meals being taken down the back from where they are stored.
I have one question and that is
"what aircraft were you in and where were you seating when you saw the crew walking through with these meals after you missed out on your
choise"?
By the way it's on domestic flights usually that you have a choice of a hot or cold meal.On international flights there are a number of hot meal
choices.So normally you would not miss out on a hot meal although you might not get your
choice of which hot meal.
