A person bought a loaf of bread in Paris where no pas yisrael was available. He ate half of the loaf in Paris. He then flew with what was left of it to London. In London pas yisrael was readily available. The question was could he finish eating this loaf of bread in London. He submitted the question to a posek. I don&rsquo;t recollect the answer, but in this case it was theoretical, since by that time the bread was no longer fit to be eaten!</span></span></span></p>
