Final answer:
The bartender could use the survey results to determine the most popular beverage, analyze trends, and introduce new beverages based on preferences.
Step-by-step explanation:
Based on the information provided, the bartender could use the results of the survey to determine which beverage is the most popular and focus on promoting or stocking that particular beverage. For example, if the survey shows that the majority of people surveyed prefer soda, the bartender could make sure to have a wide selection of sodas available and promote soda specials or discounts.
Another possible action would be for the bartender to analyze the survey results and identify any trends or patterns. If certain demographics or age groups have a clear preference for a specific beverage, the bartender could tailor their offerings or promotions to cater to those groups.
Lastly, the bartender could use the survey results to introduce new beverages based on the preferences of the surveyed individuals. For instance, if a significant portion of the respondents listed fruit juice as their favorite beverage, the bartender could consider adding a variety of fresh fruit juices to the menu.
