I voted no. I have a spider that will never hesitate to bite me. I took to my fav LPS to breed to one of their females and the pet shop owner handled him without so much as a strike...

I handle the spider pretty often, granted I work two jobs, and have a family (but take care of my pets!) but was just amazed to see him calm down like that in another persons hands. Maybe its because I am expecting to be bit that I am bitten? Who knows.

The only reason I voted no is because I don't think they really know who the owner is, I think its more along the lines of if the snake is ok with the person (maybe they smell me expecting the bite). But I have been bitten as well from a calmer snake!?!? Sorry to base this off bites, but I mean, thats like their love right?!?
