Ah, good times.
Part of that is just knowing your enemy. You don't negotiate with guys like Loki or Lilith, they'll always screw you over regardless; assuming they don't blackmail you into poverty before running away without doing anything. Course the demons and gods tend to stay true to their mythology so it is a bit easier to know what to say in most regards once you get alignment down.
