Infinite Money
Keep going in and out of any tavern until there is a viable officer candidate
waiting to be hired. Tell them you don't think they are worth what they are
asking, they will lower their price, then say they are still not worth their
fee. Keep doing this, and eventually it will turn into a negative sum. The
amount of money you hire them for (which will be shown as a negative amount,
-5000 for example) will INCREASE your gold instead.

NOTE: I discovered this with a commerce skill of 7, and each time I performed
the trick, the amount went down by 700. With a lower skill rating, they
sometimes refuse to lower their price.

Run Away
If you run into a group of baddies you think you cannot beat then run away and
go past the last point where the game loads and they won't follow you.
