What is the consequence of neglecting to check IDs consistently?

Neglecting to check IDs consistently can lead to significant legal and financial repercussions for an establishment. The correct answer highlights the potential fines and risk of losing the liquor license, which are serious consequences that can impact a business's ability to operate legally.

When a server fails to verify the age of patrons, it increases the likelihood of serving alcohol to minors, which is against the law. Law enforcement agencies actively monitor compliance with age verification laws, and establishments caught not adhering to these regulations can face heavy fines, legal actions, and potential suspension or revocation of their liquor licenses. Losing a liquor license can severely affect a business's revenue, as it cannot sell alcohol without this essential permit.

The other options, while they may sound appealing, do not accurately reflect the serious implications of failing to check IDs. For instance, increased sales revenue may happen in the short term but is not sustainable without complying with the law. Improved customer relationships might occur if patrons feel comfortable, but this is ultimately overshadowed by the risk of legal violations. Lastly, the idea of having no consequences if caught is misleading, as the law does impose penalties for such oversights. Thus, the primary focus should always be on compliance to ensure the business remains operational and legal.
