I haven't seen the film, but just from that statement I get this:
He just takes the prominent world issues mentioned in his stride, he is unsympathetic, hardened and indeed cynical in his view on life, and his place in the world. As he feels disjoint, for whatever reason (you probably know - perhaps he even strives to remove himself from such issues due to his own past), from these issues he easily and readily dismisses them, preferring to indulge himself in a minibar.
I don't know if that is congruent with his representation in the film, but from that short line this is my picture of such a person.
EDIT: This only if the study guide is correct in saying it attests to his cynicism, otherwise it could have been said in sarcasm or as a "go help then come back and rest" thing...
