Cafe Nola is located in Hampton and business is very busy during lunchtime. Chrissie, an accountant who works in town, generally has her lunch at Cafe Nola. One day, Chrissie, who at the time was using crutches after a sport injury, entered Cafe Nola from the front door.Chrissie was in a desperate rush. As she came through the door, the foot of her crutch landed on a hot chip (which she didn't see because she was rushing), and slipped. She fell to the ground and suffered a lower back injury from the fall, including two dislocated discs. Later it was found that Cafe Nola had reduced regular cleaning to two times a day from six times and had cut half of their cleaning staff. There had been three incidents in the last two months where customers had slipped, although none had resulted in serious injury.
