I agree with KMG. Unless you're ready to buy an animal, there's really no need for an exam. What exactly are you examining the BP for?
I'm sure the policy is set for a reason. My local reptile shop has a similar policy. The owner of that reptile store always says "we're a store, not a zoo". Lol. On a serious note though, I'm sure they get a lot of requests "to examine" the animal. You got to take in consideration the outside germs/parasites/mites they'd be opening their animals if they let everyone handle them.
I feel like "looking the snakes over" thing comes from expos where breeders try to connect with the buyers y letting them handle their animals.
