I don't want to speak for the OP....but for myself...
The FA's eating the leftover/extra BE meals is not an issue... If it is going to be wasted anyways they might as well enjoy...
HOWEVER eating it in plain sight of a pax is just not...I'm not sure what the right word for it...just seems like poor taste.
I've been chatted with FAs in the galley while they were eating and that is one thing...but to sit in the jump seat facing pax just seems kinda unrefined...
It is the little things that really separate DL and the likes of SQ, MH, CX, EK, etc... on the TPAC and Asia routes...
