yotty, do you mean the liquid disposal? I love those things and wish my current employer would fit them, having to get rid of liquids down the lav looks disgusting and is a pain in the rear end....
The GWDU my former airline had was a dream, you could put milk, wine, coffee etc down it all at the same time, even milky cereal or youghurt if you needed to. (Must admit many crew put stuff down it just for fun to see how it worked since most had never seen one before!)
