Assistance?

How do you hire and assistant as a Vampire? I mean a lot of vampires have day time assistants in books but rarely do you hear oh I got this one because blah blah blah. So what is that interview like? Are you trustworthy? Do you hate the undead? Are you likely to abuse my hospitality? Even if you turn them into a ghoul or Rehnquist (sp?) how do you know you can trust them when it's daylight? There have been more then one tale of going through an daytime helper to get to the vampire. And beyond whether you trust them or not. What if they just aren't dedicated to you? What about being stuck in a natural disaster. Will they risk their life to save you? That's the kind of thing you only know if you're in the situation and then it's to late.

Have a nice day :)
