Like Nathan, I roll for many things too, when they come up. Or let the player roll for some things. The best is when they find gold. I "borrow" the method from Warhammer Quest. Let someone roll as many d6's as they like, that's how much gold they find, but if any of the dice come up 1 there is no gold! You should see the player squirm when faced with the classic conflict of fear versus greed :)
