No Rice! is a Cincinnati-style chili restaurant and brewpub that specializes in serving freshly prepared chili dishes with homemade spaghetti noodles. One day in the restaurant's bar area, a patron accidentally dumps his meaty bowl of No Rice! Chuck Chili all over the floor and notifies a waiter of the spill. Thirty seconds later, an employee carrying a big foam poster (with the international prohibition sign overlaid on a bowl of rice) is shuffling by, slips on the dumped chili, and breaks a hip. If the employee later sues No Rice! for negligence, the employee will have to prove that No RIce! failed to use _______ care in the situation.
