Customer, aged 20, went into Store at approximately 6:45 p.m. to look at some suits that were on sale. The clerks were busy, and one of them told Customer that he should wait on himself. Customer selected three suits from a rack and went into the dressing room to try them on. Signs posted on the walls of Store stated that 58 closing time was 9:00 p.m.; however, because of a special awards banquet for employees, Store was closed at 7:00 p.m. on this day. The employees, in a hurry to get to the banquet, did not check the dressing rooms or turn off the lights before leaving. When Customer emerged from the dressing room a few minutes after 7:00 p.m., he was alone and locked in. Customer tried the front door, but it was secured on the outside by a bar and padlock, so he went to the rear door. Customer grabbed the doorknob and vigorously shook the door. It did not open, but the activity set off a mechanism that had been installed because of several recent thefts committed by persons who had hidden in the store until after closing time. The mechanism sprayed a chemical mist in Customer's face, causing him to become temporarily blind. The mechanism also activated an alarm carried by Store's employee, Watchman, who was just coming to work. Watchman unlocked the front door, ran into the store and grabbed Customer. Customer, who was still unable to see, struck out at this person and hit a metal rack, injuring his hand. Watchman then identified himself, and Customer did the same. After assuring himself that Customer was telling the truth, Watchman allowed him to leave. If Customer is to prevail on a claim against Store based on battery from the use of the chemical spray, Customer must establish that 
he suffered severe bodily harm. the spray mist was an offensive or harmful contact. he suffered severe emotional distress. his conduct was not a factual cause of the chemical's being sprayed on him
