We never saw the cocktail waitress arrive, but it does appear that Phan and Neckar have both received a bottled water. It is not the typical all in water that has been served here, so we can only assume someone brought it to them.
Wait....just as I am typing this I see the cocktail lady over at a table next to the final table. Oops, I spoke too soon. In the time it took to type the last sentence she has left the area.
