Ah, I'm glad you mentioned the old "coffee may be hot" thing. It means I can post http://www.caoc.com/CA/index.cfm?event=showPage&pg=facts.
It's all very well throwing around sayings and anecdotes and "well everybody knows..." but actually you often find that if you look into the facts before jumping to conclusions that you'll be the one who's surprised. So I'll also give you http://www.snopes.com/legal/lawsuits.asp, which is a good article from a great website that more people need to spend more time reading.
I'm still not impressed. The point is, coffee is hot. If you're upset you're burned by coffee, you deserved it, because chances are, you'll get pissy when you do it again. I wasnt referring to that case explicity. But the in general warning coffee cups of stores. If you have to warn people that coffee is hot just so you can cover yourself legally, you know your society is going down the drain. Coffee is hot, water is wet, snow is cold, and fish are scaley. It's common sense. Trump it up as much as you like, but there is a good deal of 'no common sense for me!'
@Vometia- Meh, I don't care if something is 100% anything. As long as it does it's function, doesnt taste like garbage, and I dont get sick, I just scoff at the '100% ___'
