Kathryn primarily met with clients at their offices as it was easier for them and allowed her to see their business in action. One new client, Casey Clutzy, wanted to meet with Kathryn at her office. Her appointment was at 10 a.m. but at 9 a.m. Kathryn discovered that there was a problem with the flooring. One section had lifted and caused a trip hazard. In fact, both Kathryn and Davinder tripped several times that morning. Kathryn thought about putting up a sign but forgot to do it. When Cathy came for her meeting, she tripped and fell, breaking her arm. Kathryn is very worried about whether she is liable for Casey's injuries.

Question: Kathryn is worried about any potential liability to Casey Clutzy. What, if any duty, does Kathryn have to Casey? Did Kathryn fulfill her duty? What liability, if any, does Kathryn have to Casey? Are there any defences that Kathryn can use?
