In a fairly cataclysmic life, one of the things that has always caused me considerable confusion is whether a round is one slice or two, and this thread has done nothing to enlighten me. So I usually end up with a sammo that is either half or twice the size I was expecting.

LtS, my Nan used to do that as well. Do you remember Ryan and Ronnie used to have a character who would butter and slice the loaf whilst holding it under her arm - '..and don't call Will on your father!...'
