I agree with this 100% Vexer. It would be like going into my room and touching any of my stuff...To the OP no thats not being anal at all. My brother is the only other one I trust to get my snakes out. Period. If Im home and someone asks me to see/hold them, then Im more than willing to because I think its important to educate people about them.
On another note I would compare this to if you were walking along the side walk and just went up and started petting someones dog. Even if the dog is friendly, asking the owner if you can pet it is always the right thing to do.
