to be fair, I had drank some at that point! But ya, it wasn't very full in the first place. I think we lost a little because we ordered the same drink. So the flight attendant person had a can and kind of poured it back and forth between the two cups and stopped when the can was empty, but neither cup was as full as he would have poured it if he was just pouring for one.

Step up your game, American.
