a) Warned about what exactly? That people are going to be reckless and possibly injure themselves? What action is McDonalds supposed to take to prevent idiocy? It's not a children's toy. It's for adult consumption. b) Why would I expect that it would be similar to what I do at home? It's McDonalds. They serve their coffee very hot. People like to drive to work, and still have it hot when they arrive. Also, I have no expectations of those cups other than that they are flimsy. The temperature issue is not relevant anyway because if she wasn't negligent in her use of the cup the contents would have been kept safely contained. A knife in a restaurant can cause significant damage as well if you decide to be an idiot and try to remove an eye lash from someone's eye with it. Would you say that the knife was too sharp? That it is sharper than the knives you use at home?
