I don't recall being asked anythign particularly invasive, or even anything more than 1-2 questions, sometimes no questions at all. I did get the one guy who (before I had GE) pointed out that I had forgotten to sign/date my blue slip and that it was a $50 fine. I had a moment of panic before I realized he was joking. Ended up have a laugh about it and asked if he ever had anyone actually try to pay him (yes, he did, and no, he didn't take it - "too many cameras" *wink*)
