In this case, you have the moral victory as you know he wants the beer so much its making his tatoo itch. Plus you have a 50/50 chance of picking the right path.

The beer question as a solution to the problem actually came from a famous mathemtician, whose name I have no chance of remembering, who liked beer. He also queried the behaviour of someone who is lying. Is the intent to give an answer which is always false, or is it to give an answer which is misleading.
If it is to give a false answer, then you can try to get round it with logic. If the intent is to decieve, then you can't do a 'if I were to ask you this, what would you say' question, cos the liar will give the most misleading answer, even if its logically impossible.
Hence, the beer question.
