Mary operates a convenience store, "Mary's Shoppe". It has become a hangout for teenagers. She hired Frank to act as a security guard between the hours of 3 pm and 5 pm, when the store is at its busiest. Mary noticed that a young woman named Shelley, whom she had previously suspected of stealing, was acting suspiciously. She notified Frank, who approached Shelley and said in a loud voice and an accusing tone, "Come here. I've got a few questions to ask you." Shelley realized that Frank was acting on instructions from his employer and shouted over his shoulder at Mary: "If you've got a problem, come over here and speak to me yourself! I'll smack you silly!" At that point, Frank lunged at Shelley in an attempt to restrain her. He grabbed her arm, but she managed to wrestle free and run out of the store. Is Mary's Shoppe liable for any intentional torts?
