Well think about all the really subtle morphs out there. If you were bagging up 1000 hatchling bp's and had to do it fast you don't have time to really notice a subtle pattern? Plus these bp's were screened already for morphs so why even bother. I'm fairly sure the guy doing the bagging just sits there all day bagging up snakes for export and doesn't really care too much so long as they are bagged and he gets paid.
