Washing is labour intensive, that is why they (airlines) don't do it.
That is probably why the airlines overtly separate waste and recycling, but in the end, we don't see what they do with their "recycling".
Every time I fly VA, they come through, asking any rubbish, any rubbish, when the annoucement comes on to "prepare the cabin for landing".
OT, talking about flying, flew SQ and (Air)NZ, over this past weekend, in J for SQ, and in premY on NZ, their napkins, (the things you wipe your mouth with after eating), is a type of papery sort of thing now, not the true fabric of the AN days of old (Ansett), when flying J.
Flying VAd shorthaul in Y, when asking for water, its also now in that small petite 250mm container.
No glass for us plebs in Y.
Pretzels, now, is that filling for the stomach ADL - BNE or vv?
