the last one, that should be really disgusting and awful ...

Why the biscuits are like that? could be simple as:
The loader drop it while shipping it ...
A customer was checking those and drop them ...
Another customer tried to pick it up, but he drop another one instead ...

Someone saw him doing that, did the same to get even ...
Someone took it already home and after a fight why did he bring it, he return it again ...

or maybe you are just unlucky enough to have those biscuits broken every time you buy them. I consider you luck as I'm buying those to make cheese cake, that would save the time crushing them :)

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. (Gautama Buddha)
