CASE: KUEHN V. PUB ZONE Facts: Maria Kerkoulas owned the Pub Zone bar. 0 She posted a sign prohibiting any motorcycle gangs from entering the bar while wearing colors (insignia for their gangs). 0 Members of a gang came into the bar, all wearing colors, and though Kerkoulas saw their colors, she allowed them to stay for one drink. 0 They later followed a customer named Karl Kuehn to the men's room and savagely beat him. Lower court: 0 Kuehn sued Pub Zone and the jure awarded him $300,000 in damages. 0 The trial court judge overruled the jury's verdict, claiming Pub Zone had no duty to protect Kuehn. Appellate court: 0 The possessor of a business is normally under no duty to exercise any care, until he knows or has reason to know that the acts of the third person are occurring, or are about to occur. The gang was collectively known to Kerkoulas to engage in random violence. A duty to take precautions against the endangering conduct thus arose
