Final answer:
You should not pour a stronger drink for a customer who tips well, as it is important to practice responsible service of alcohol for the safety and legal compliance of the establishment.
Step-by-step explanation:
In the context of professional and responsible service in the hospitality industry, it is not ethical or legal to pour stronger drinks for customers who tip well. Adhering to responsible service of alcohol is critically important for the safety of patrons and the legal compliance of the establishment. While it can be tempting to reward a generous tipper with a heavier pour, doing so can lead to over-intoxication, which poses risks to both the customer and others and can result in liability issues for the bar or restaurant. A professional bartender should maintain consistent pour sizes regardless of tips to ensure equal treatment of all customers and to uphold the standards of responsible alcohol service.
