I know everyone is having fun, and I hate to be a wet blanket, but:
S1(1) and S2 Criminal Damage Act 1971 makes it an offence intentionally to damage or threaten to damage, without lawful cause, property belonging to someone else.
Whoever binned your sushi probably committed that offence; but that does not give you lawful cause to damage Fridge Hogger's property - or the fridge.
I don't suppose for a moment anyone will call the police over this - but I might be inclined to check my employment contract to see what my position would be if Fridge Hogger complains to management that I have committed an offence against her on work premises.
Just saying.
