So for the most part I understand the building income system, and how the economics system out of Ultimate Campaign works except for a conflict between NPC profession rolls and Building income. The question is Why are NPCs entitled to a profession roll while they are working at an establishment they do not own?
This came up when I offered the Barmaid if she would like to be the manager of our inn while we went to kill Goblins and her response was "No, I make more than 2 gold in tips," I and my character assumed she was stealing from the inn. Her earnings amounted to 60% of the building's total earnings. Granted We (the Party) just Got the building and it is considered "broken," but that is all the more reason why a barmaid earning 2.5 gold per night seems weird. My understanding is that the average commoner makes between 1-3 silver a day. So, I assumed that she was stealing from the Inn, and did a rundown of the inn's operations and books. My GM said they came up clean, which made me more suspicious. I admit I may have gotten a bit cantankerous at this point but this character was made to be an economic guru, and I thought I had a pretty solid mastery of the building income rules in preparation. so I pushed it.
The answer I got from my GM was, "she is using her profession roll during her shift to make the money, it reflects the tips she is getting." and apparently he had it verified by something on the forums, said by one of the devs. I can't find the post, but I am sure he is telling the truth.
So, I ask again, Why? Why is the Tip check calculated independently of the Inn's income check. It seems like the checks should influence each other. A good Barmaid should increase my Inn's reputation, and a profitable Inn should increase the tips.
I am asking for clarification, because the issue is kind of breaking the immersion for me and I want to be able to enjoy the game.
