Even if you turn the knob all the way clockwise will a toaster really set fire to what's in there? I've had a few bits of bread turn into charcoal, but never anything approaching conflagration.
But if we could try and rewind to the original issue...
If there are sockets on the wall behind and above a small worktop, and appliances such as toasters and kettles are plugged into them, how does that create problems of cable clutter on the worktop which would be solved by having sockets on the wall behind and below the worktop?
It's all very well us coming up with ideas, but I cannot understand the validity of the OP's concern.
