Johnny regularly engages Ian to clean his pool. One day, Ian parks his van in the driveway in front of Johnny's double garage, which as usual is closed and locked while Johnny is at work. While Ian is cleaning the pool at the back of the house, a sudden hail storm causes damage to Ian's van. Ian insists that Johnny compensate him for the damage to the van, since it occurred while Ian was on Johnny's property, and would not have happened if Johnny had left the garage door open for him. Should Johnny be compelled to compensate Ian? Assume that Johnny owed Ian a duty of care, and focus upon whether or not that duty of care was breached.
