Does yours have a bad attitude?

I have had my little boy, Spud, (I'm not a snake expert but his mother was an albino, his dad normal. I believe that makes him het.) for a bit over 2 years now, and never has he once cracked. By that I mean no hissing, nipping, hiding and tensing. He rarely is ever frightened, and is extremely sociable. I believe he actually enjoys his handling time. When I walk by his cage he comes out of his hidebox and bumps at his lid (weighed down.)

I know that BPs are one of the best tempered snakes, or so it was said by his breeder, and so I have learned from some of the feedback on this site.

Sadly, my not-so-friend-like friend owned a BP who apparently had a bad attitude. He hissed at often, apparently, by this girl. Anyways, I haven't heard about the poor girl often and I hope something bad hasn't happened to her. I can assume he might have upset her to make her this way -- he was not the best pet owner... but anyways. Has anyone ever had, or heard of, a "nasty" BP?
