One thing that I keep wondering. He has a private bathroom in his room where he can drink out of the faucet. Why doesn't he do that when he is thirsty? But then again not all countries have clean faucet water that is save to drink, come to think of it. Let's go with that (otherwise he is even more dumber than I thought).
I'm kinda hoping the developer keeps this not drinking trend going as it anoys the heck out of me, but also makes me laugh.
