I just reviwed the page before submitting this and badger3k seems to have got in ahead of me. Damn you, badger.
Let's say there are two cakes. The cake dumped upon the ground could be shown, scientifically, to be contaminated by real life bacteria. You could take swabs and show a difference: Germ-laden cake .... nice cake --- not the same! You can't recommence proceedings with the contaminated cake. You can still feed the other, pristine, cake to your guests with a clear conscience, but if one guest gleefully devours the cake, while another "saves a piece for later", you don't get to demand the death of that person.
