We were away over the weekend and we had a house sitter.
Left the usual instructions:
Cats are locked on the 3rd floor - don't let them out.
Lock all the doors when you leave.
Make sure the security system is on.
Yada , yada, yada.
What we didn't tell them (and thought that any sane person would realize) was NOT to put the plastic bottomed ELECTRIC kettle on the gas stove.
We came home to a destroyed kettle and one burner of the gas stove covered in burnt, black plastic. Luckily the stove has separate burner heads and easily replaceable grates and the plastic only took out one burner head. We were lucky as this could have been a total disaster.
And the house is still standing and the cats are alive.
For ostensibly smart people our sitters were amazingly dumb.
The bottom of the burner head - the orange wire is the ignitor which still works and the silver pipe is the venturi tube which was also undamaged.
The unholy alliance of cast iron and plastic
The former kettle.
