Surely more realistically:-
ET = Peanuts at a bar
WT = Asda/Morrisons Ready Meal
WT+/CE = Tesco Ready Meal
J = Sainsburys Ready Meal
F = M&S/Waitrose Ready Meal
There is no food that BA have served me in any cabin (and I have only done CE/F/J) this year that has been in any way shape or form approaching restuarant quality
