Okay.. let's review:
1. Alys and Company arrives home
2. Alys and company go to the store
3. Alys and company speak to two teenage girls who tell them they're going to sneak out of the inn at night so they don't have to pay the 90+meseta that they are being rightfully charged.
4. Girls get caught
5. Alys and company visit the two brats in jail
6. Fast forward some 20 - 25 levels in the future and some guy from Uzo puts up a reward for his two missing girls.. a 2000 Meseta reward!!!!
7. Chaz and company bail the cheap brats out of jail for 2000 meseta
8. Girls go home to their dad
9. Chaz and company go to the guild and recieve 2000 Meseta, ending back where they started in their financial situation
10. *!?!?!
Now that we have the facts... We know that the girls Father is a rich guy. THe dude posted 2000 meseta for their pretty little heads, which is more than enough for a most expensive armors in the game.
Now you tell me... If the girls came from so much money... Why didn't they just pay the lady at the in the lousy 90 meseta?
