Final answer:
Courts of law expect workers in the liquor service industry to promote responsible alcohol service and not discriminate based on appearance.
Step-by-step explanation:
Courts of law expect workers in the liquor service industry to promote responsible alcohol service. This means that workers are responsible for ensuring that customers are served alcohol in a safe and responsible manner, including monitoring the amount of alcohol consumed and preventing excessive drinking. Workers should also be aware of signs of intoxication and refuse service if necessary. Discriminating based on appearance is not an expectation of the courts and can be considered illegal.
