So this week I learned that I'd failed my most recent dictation exam with Mrs S.

During the list reading for the previous shop, I thought Mrs S had asked for frozen Rosti (for which I was pleased to find in the freezer section at the world's politest supermarket).

It transpired that she'd actually wanted frozen Roti...clearly something very different, and much better suited to accompanying a curry, which had been her plan.

My only saving grace was that this wasn't to be found in the freezer section of the world's politest supermarket, but as we've always been told in exams, always double check the question before starting the answer...
