Final answer:
Counting glasses is not the most accurate method to track alcohol consumption due to variables like shared drinks and spillage. A better approach is to measure the volume and observe behavior.
Step-by-step explanation:
The statement that the best way to keep track of how much a customer has had to drink is to count the glasses delivered to the table is false. While counting glasses can provide a rough estimate, it does not account for potential variables such as different people drinking from the same glass, spillage, or customers sharing drinks. A more accurate approach involves measuring the actual volume of alcohol consumed, paying attention to the specific beverage types and their alcohol content, and closely observing the customer's behavior.
