Hi James!
It was clear what that money was ... just need to see the way the left the money on bedside table (and the simbology of that) - why not deliver directly to them?? - and the way she keeps it in the the drawer and then celebrate receiving it... No one expects that managers or tenants will assume what that was (it was really bad luck to them that someone saw it)... And at that second visit the same seems to happened but this time otto and client was smarter and left the apartment to outside cams.. and when arrived girls waited that the guy left the living room to ask otto if it's all done and all included..
The video it's on archive and just needed to check after 05:33:30 + - and see lola and girl gestures and behavior...

The title of video also helps to understand that "the sexy games started after that"
I know the answer will be it was nothing like that... It was just a coincidence...
