Actually a large percentage of VL does take place at Schneiders. It's usually where the aristocratic characters meet the non-aristocratic characters. Top of my head, recent meeting scenes that took place at Schneiders are Angsar and Tanja discussing her blackmail of him, Nathalie and Lars (including all of them finding out that baby Sophia was alive), Angar and Olivia (when he was backmailing her), Sarah and the models (when she was taking drugs and making a scene).Adrian, Kitty and Sebastian also frequent it rather often.

Larger parties also usually take place there (Baby Sophia's christening after party, the celebration of Sarah's modelling campaign, the goodbye party for Carla's wife).

The Schneiders basically is the No Limits for the older characters.  

The No Limits, the Schneiders and the castle (though mostly for the family dinner or breakfast scenes, the kitchen where they interact with the staff and the hall where various people come to confront them) are the biggest general locations. The most important "home" locations are the Ollian flat, the Brandner family home (Lydia's family+Arno) and Carla's flat. Occasional places we see are Tanja's modelling agency (usually just so people like Ansgar and Lars can storm in to insult Tanja or to have Olivia and Kitty gossip) and the hospital where Leonard works and all sick characters are brought (recently the place where Adrian and Constantin had their blackmail and kidney transplant story, where Carla had her breakdown and heard her baby crying through the door, where Sarah went after taking bad cocaine and where both Sarah and Jana recovered after their accident). 

Once in a blue moon (at the moment) sets are the main room in Gregor's flat, the Brandner Bau construction site, Carla's office and Sebastian's room at the castle. And of course various locations. 

So really, as far as visible jobs, there really isn't anything he could do other than assisstant at Tanja's modelling firm (blegh), works as a servant at the castle (more blegh) or become a construction worker together with Fabian and Judith (yeah right).  I guess he could work for Carla's bank, but really, that doesn't suit him either.

Personally, I don't get the need to give Olli a different job. Considering its his aunts place it's probably gonna be a pretty relaxed real. And they could always nominally give him a higher, more managing/organizing function there while having him essentially do the same thing. 

Lola...I felt Olli's reaction played out more naturally with his intense anger. Most people would react this way within the first day or two of finding out they were taken avantage of and dragged into a crime because of a family member's behavior. I don't think displaying sadness or disappointment at the person would come to mind within the first day, at least. More realistic would be you wanting to kick that person's ass for dragging you into the fray. Which is exactly Olli's response through how furious he is and threating  to go to the police if Olivia doesn't come clean.

I felt the scene played out accordingly.
