One way to protect yourself from a liquor liability lawsuit is to?

Serving alcohol to minors is illegal and can lead to legal consequences, hence it does not protect from a liquor liability lawsuit. Ignoring customers can also result in lawsuits and does not protect from liquor liability. Limiting the number of drinks per hour is a helpful strategy but solely relying on it may not fully protect from a lawsuit. Observing customers for signs of intoxication is the best approach as it helps prevent over-serving and potential liability issues.
