I definitely wouldn't take the snake to that vet again -- that is too funny that he didn't want to pick up your BP (not really funny, but I think you know what I mean).
I had a simiiar experience once when I took my first bp about 10 years ago to the vet. The vet was actually okay, but I could tell the assistant was afraid of the snake. She kept on holding him by the neck (right behind the head) like he was a vicous rattler that was going to strike at any moment. I mentioned to her a few times that she didn't have to worry, and by the end of the check-up she finally seemed to relax a bit.
Later,
