Ok picture the scene. You're at home, the sink is full of hot soapy water, you're really excited because you're about to do the dishes. Then out the blue the phone rings -it's a political prisoner using his weekly phone call to find out what the latest products deleted from the Asda Smart Price range are. If you return to your dishes he'll have wasted his call and won't have any Smart Price intel to trade with the other prisoners putting him in danger. If you stay on the phone the water will go cold. Your maverick little brain gets to work and BINGO! You realise that if you slide an old metal tray over the sink you'll have a hot tray. It's pretty simple if you think it through.The baking tray thing is just sheer unadulterated madness.
What problem is she solving? Someone please explain!?!
