What method can be used to estimate a customer's BAC to prevent intoxication?

Keeping track of the number of drinks consumed is a crucial method for estimating a customer's Blood Alcohol Concentration (BAC) because it provides a straightforward way to monitor alcohol intake over time. By understanding how many alcoholic beverages a customer has had, staff can better assess the potential for intoxication and intervene if it seems like a customer is drinking excessively.

This method allows servers and bartenders to maintain responsibility and make informed decisions about serving additional alcohol. It also aligns with legal and ethical standards for serving alcohol, as it helps prevent over-serving individuals who may already be approaching or exceeding allowable limits.

Other methods, while potentially helpful in certain contexts, may not provide a reliable or comprehensive assessment of a customer's BAC. For instance, decreasing the serving size of drinks may help, but it doesn’t directly inform staff about how much alcohol an individual has consumed in total. Measuring observable behaviors can provide insight into someone's potential level of intoxication, but it can be subjective and variable. Limiting beverage options to non-alcoholic drinks certainly prevents intoxication, but it does not aid in estimating BAC if alcohol is already being consumed.

Using a clear and consistent method like tracking drink counts supports responsible service and effective prevention of over-intoxication.
