Mr$.$ Burns provides security services for the Nuclear Power Plant $($Plant$")$ in Springfield. Mr$.$ Burns employed Simpson as a security guard. On the day of the accident, Simpson was assigned to guard duty at Gate $4,$ the northeast entrance to the Plant property. Security guards at Gate $4$ worked eight$-$hour continuous shifts, with no scheduled breaks. However, employees were permitted to take ten$-$ to fifteen$-$minute unscheduled lunch and restroom breaks.

When taking their lunch breaks, Gate $4$ guards generally ate a bag lunch but occasionally ordered take$-$out food from the sole restaurant within close physical proximity to Gate $4,$ Moe$$s Tavern. Moe$$s Tavern was located directly across the street from the Plant, approximately $150$ to $250$ yards from Gate $4.$ The tavern's menu was posted near the telephone at Gate $4.$ Aside from vending machines located within a nearby Plant office building, Moe$$s Tavern provided the sole source of food accessible to Gate $4$ guards within their ten$-$ to fifteen$-$minute breaks. Indeed, Moe$$s Tavern was the only restaurant in the immediate area. Whether they brought their lunches or ordered from the tavern, Gate $4$ guards were expected to eat at their posts.

Shortly after $11$:$00$ a$.$m$.$ on the day of the accident, Simpson noticed a lull in the traffic at Gate $4$ and decided to get a cup of soup from Moe$$s Tavern. He placed a telephone order for the soup from Gate $4$ and then drove his automobile to the tavern. He intended to pick up the soup and return to Gate $4$ to eat at his post. She expected the round trip to take approximately ten to fifteen minutes, as permitted by Mr$.$ Burns unscheduled break policy. On his return trip, however, he collided with plaintiffs' motorcycle at a public intersection just outside the Plant$$s property. Both plaintiff and Simpson were injured.

Discuss. Who will be liable for the damages?
