Some entertainments , such as at large festivals ( whether religious or secular ) , concerts , clubs , parties and celebrations , involve big crowds . From earliest times , crowds at an entertainment have associated hazards and dangers , especially when combined with the recreational consumption of intoxicants such as alcohol . The Ancient Greeks had Dionysian Mysteries , for example , and the Romans had Saturnalia . The consequence of excess and crowds can produce breaches of social norms of behaviour , sometimes causing injury or even death , such as for example , at the Altamont Free Concert , an outdoor rock festival . The list of serious incidents at nightclubs includes those caused by stampede ; overcrowding ; terrorism , such as the 2002 Bali bombings that targeted a nightclub ; and especially fire . Investigations , such as that carried out in the US after The Station nightclub fire often demonstrate that lessons learned " regarding fire safety in nightclubs " from earlier events such as the Cocoanut Grove fire do " not necessarily result in lasting effective change " . Efforts to prevent such incidents include appointing special officers , such as the medieval Lord of Misrule or , in modern times , security officers who control access ; and also ongoing improvement of relevant standards such as those for building safety . The tourism industry now regards safety and security at entertainment venues as an important management task
