It depends which cart we're talking about here...
Drinks service on long haul (economy cabin):
Juices, water, ice, lemon, napkins, plastic glasses, ice tongs, the rest of the drinks are in the trolley.
Meal service on long haul (economy cabin):
A box with meal choices and a box with wine (red/white) and plastic glasses. There's water on the tray, so therefore not on the trolley. Although I know some people put soft drinks/juices on this trolley, it's not supposed to be there, strictly speaking, however I don't have a problem with crew wanting to put these items on.
