Re the Warburton/toaster manufacturer, I'm thinking the both of them.
Warburton's should take responsibility for producing the darned bread in the first place. If bread didn't exist, I wouldn't have attempted to make toast.
The manufacturer's of the equipment are without doubt culpable. How irresponsible to make a toaster produce toast that isn't automatically cooled down to the level of my sensory nervous system!
The irresponsibility of everyone else, eh?
I reckon I'm looking at suing for at least half-a-million
