Or perhaps bad handling before it actually gets to the professionals doing the jabbing?
Yes you are right. Going back to the anecdote it was concerning the preparation/storing etc. not the injection practice itself.
This suggests it is the Pfizer vaccine. The AZN vaccine from what I know appears little different to a mass produced, fridge stored, vaccine such as used for many long standing inoculation programmes. It shouldn't be difficult to manufacture and store, although as a "new" vaccine I think the batch testing regime is still more rigorous than other vaccines.
I would be surprised if there was an systemic failure in the vaccine at the point of injection (pun unintended).
