The lights are on
As of today, I'm not sure if this is fixed or it only works for myself, but when you complete the quest that you have to get the people to fufill the weird fetishes for the atomic wrangler, the robot is one of them. You will find the robot roaming the wrangler for people to do "bussiness" with. If you hire him he'll go to your room. After you do him once he'll start leaving. When he starts to walk talk to him and ask for his services, but don't go through with it! Quickly hit back and you will recieve 5 caps. Rinse and repeat.
It's a slow process but for lot's of caps, I'll do anything.
