Skills on Sunday - From 3e/3.5e - Profession http://www.d20srd.org/indexes/skills.htm
This is one example of how 3.5 tried to micromanage everything and turn it all into dice rolls. If a PC has a non-adventuring life doing some kind of profession—such as a bard who runs an inn when his group is not adventuring—then that can almost always be done a combination of role play and simply the DM determining the local reputation of the innkeeper as an adventurer and modifying the income appropriately.
Back in the day, I used to play bards all the time, and running inns was my favorite non-adventuring profession. I would turn each inn into a museum of my character’s adventures, displaying tacky and sometimes exotic or frightening mementos of our party’s adventures on the walls of the common room where my PC could boast of stories of the adventures and point to the evidence to prove they were true. But in 3.5 they wanted to turn that all into crunchy dice rolls so you could experience boons and busts that may or may not have anything to do with stories the DM had planned or may or may not reflect what is going on in his or her campaign world. To me, this is just the kind of thing that doesn’t need to be in a game system, but it’s there for people who want it.
