Not my argument.

A simple oven failure. A blown element.

All I said to the couple was "I'll fix it now if you go and fetch the part"

I then spent ages explaining where the shop was that sold the part. Both of
them looked blank until I said it was next to the Sex Shop. Then she said
"Oh, I know where that is".

Then argument started.

They still have no working oven.
