I've put a hot griddle pan (yes, I know!) down on the kitchen worktop
and now have a bubble in the surface around 10mm long and 5mm wide. It's
a couple of mm high and has a fine crack across the top of it. The
worktop is a one of Formica's finest textured in black and grey.

Anyone able to advise on a repair other than 'replace it all'. I don't
have an angle grinder, but I do have a couple of cans of WD40...

Management has stayed calm. So far.
