Anyone whose ever eaten food prepared in a restaurant, fast food outlet, carnival, fair etc has eaten their fair share of dirt, germs whatever - just a fact of life (that we all like to ignore! lol)
My DH likes to quote a fact he read a long time ago, that on average every human will eat 7 spiders in their life! So scraped off cake with fresh icing - meh!!
Dont we all have those moments - after a disaster - when you stand still in time and think "WHY did I DO that!"

Turned out great!
