in the US, it's been going on for ages..
like hisk said:
Coffee is hot
Do not iron clothes while wearing them
and more..

just that i didn't think the UK was following them down that
horrible path 
Yeah, if memory recalls, the 'Warning: Hot Coffee' on McCrap's
coffee cups was because of some lawsuit years ago.
The story goes that some stupid woman bought some coffee from a
McCrap drive-through. She placed the cup full of scalding-hot
coffee between her thighs. 
Then when she accelerated away, the inertia caused the coffee to
spill, causing third-degree burns over her thighs and crotch.
She successfully sued McCrap. 
Damn...... talk about a total lack of personal
responsibility.
