Sleeman had just purchased a new luxury automobile, and decided to use it that evening to drive his wife to a new theatre production in the city centre. As he approached the parking lot adjacent to the theatre, he noticed a long line of vehicles waiting to turn into the lot entrance. The exit lane, however, was clear, and he made the instant decision to enter the lot by the exit lane. Once inside the lot, he stopped his car in order to obtain a parking ticket. An irate lot attendant came over to him, complaining that he was not to enter the lot by the exit lane. Sleeman apologized, and attempted to back out into the street, but at that point, both he and the attendant realized that it would be impossible to do so, given the heavy road traffic. Exasperated, the attendant took Sleeman's money, obtained a parking ticket from the attendant in the office, and handed it to Sleeman without comment. He then slipped into the driver's seat in order to park the vehicle. The time of year was late winter, and there were patches of ice on the paved lot. The attendant, who was now annoyed with Sleeman, accelerated the vehicle down the lot, but was unable to stop the car on the ice. He collided with another vehicle parked on the lot, and seriously damaged Sleeman's vehicle. When the parking lot owner refused to accept responsibility for the damage, Sleeman instituted legal proceedings. At trial, the parking ticket was introduced as evidence. The ticket contained the following words printed on the back: NOT RESPONSIBLE FOR LOSS OR DAMAGE TO VEHICLES HOWEVER CAUSED. The lot owner also testified that on the side of the office where vehicles enter, a large 1-metre-square sign provided the same message. Discuss the arguments that each of the parties might raise in this case, and render a decision.
