Indeed.
As for the McDonald's incident the coffee was indeed hotter than what was reccomended by McDonald's standard code by being 20 to 40 degrees F hotter. That particular McDonald's coffee maker/holder was malfunctioning and the owners of that particular store did nothing to fix it because it was their thinking that the coffee will cool down over time.
Well, the woman got her coffee, placed it between her legs and drove off. The coffee spelt and cause severe burns in that region. If memory served a docter stated for the plaintiff stated that if the coffee was in normal temperature range the burns would not be as severe.
