BA also have their "raid the larder" so you wander off and nibble/drink as you like.
I had heard of that. How does it work given that as soon as you pull the curtain open, you are made to feel you are disturbing something? Worked well with VS where the galley was the open section in the tail fin, and more accessible. I didn't see one person try to raid anything all day. I suspect it's not exactly advertised.
