Which of the following is NOT an acceptable bar-service guideline?

The guideline stating that cocktail napkins should not be touched and should be placed for guests is considered an unacceptable practice primarily due to considerations of hygiene and customer service. The expectation in bars and catering is to provide a welcoming environment, which includes attending to details that enhance the guest experience. While it’s important to keep items clean and properly presented, engaging with the settings, including placing napkins down for guests, can convey thoughtfulness and help create a more pleasant atmosphere.

In contrast, the other options focus on operational practices that ensure efficient service. For example, ensuring the right amount of alcohol is opened in advance helps prevent delays in service, and serving every drink with a cocktail napkin promotes cleanliness and prevents spills. Likewise, the idea of refreshing drinks with new glasses can enhance the guest experience by ensuring they enjoy their beverage in a clean vessel. Thus, these practices are recognized as industry standards for effective bar service.
