Which of the following is a common violation of liquor laws?

Serving alcohol to minors is a significant violation of liquor laws and regulations in many jurisdictions. These laws are put in place to protect the health and safety of young individuals who are legally prohibited from consuming alcohol. The rationale behind this prohibition includes the potential for alcohol abuse among minors, the risk of impaired judgment, and the associated dangers such as accidents and injuries.

When establishments serve alcohol to individuals under the legal drinking age, they not only face legal repercussions—such as fines, loss of licenses, and possible criminal charges—but they also jeopardize the safety of minors and the integrity of the community. This violation can lead to severe consequences for the business, including increased scrutiny from authorities, which may impact their operations and reputation.

The other options, while they might have their own legal implications, do not pertain to the critical issue of protecting minors and their health. For example, while offering discounts for cash payments can raise concerns about tax avoidance, and hosting public events without permits can involve regulatory compliance issues, these violations do not carry the same level of urgency and impact as the protection of minors from alcohol consumption. Likewise, advertising on social media, if done in compliance with laws, isn’t inherently a violation but may require adherence to specific marketing regulations.
