Quote: "Otherwise, you can only get soft food in squeeze tubes at room temperature."
Why do you think that's safe?
One over-enthusiastic squeeze and you choke to death.
My sympathies are with the old lady on this occasion (I generally think people should be responsible for their own actions - but, equally, food or drink should be "fit for purpose").
A few years ago my wife and I went for a meal in a local inn. When food is served to you on a plate you expect to be able to eat it - on that occasion my mouth was severely scalded and blistered by the first mouthful. I didn't sue - but never went back. I think it was irresponsible of the company concerned not to warn me that the food would be dangerously hot for some time.
I really don't understand why some of you think that it was the old lady's fault. Coffee is supposed to be drunk. From the sound of things she would have been scalded if she had tried to drink it. The issue of putting it between her legs, etc, is frankly irrelevant - I'm sure I would have been blistered if I had put my meal between my legs, but that is irrelevant (and somewhat unlikely unless I've had too much refreshment beforehand).
