Final answer:
Courts are allocating increased responsibility to bartenders, managers, and patrons to ensure responsible beverage service as an attempt to mitigate problems caused by excessive alcohol consumption.
Step-by-step explanation:
Courts are placing increased responsibility on all of the above: bartenders, managers, and patrons, to provide responsible beverage service. This proactive stance is part of a wider effort to address problems associated with the excessive consumption of alcohol, such as poverty, street crime, worker absenteeism, workplace accidents, and domestic violence. By increasing accountability across all parties involved in the service of alcoholic beverages, there is hope that the negative impacts of alcohol on society can be mitigated.
