ChemCo invites Marsha Ramirez into their Hartford showroom. The showroom contains lab coats, supply carts, filter paper, hand sanitizers, and other harmless products. While browsing the products in anticipation of a purchase for her company, a piece of dry plaster wall falls from the ceiling and hits Marsha on the head, causing injury. While ChemCo does not inspect its showroom for safety hazards, it had no idea that its ceiling posted a hidden danger to others. Is ChemCo responsible for Marsha's injuries? Why or why not? What is your rationale?
