Which of these actions is necessary when a bartender encounters a malfunction?

When a bartender encounters a malfunction, the appropriate action is to report the issue and revert to manual work. This approach ensures that safety and service quality are maintained. By reporting the malfunction, the bartender communicates the problem to management or maintenance staff, who can address the issue properly without risking further complications or safety hazards.

Reverting to manual work allows the bartender to continue serving customers without relying on the malfunctioning equipment. This method can prevent service delays and maintain customer satisfaction. It is important to prioritize the reliability of customer service while ensuring that any operational faults are documented and handled by qualified personnel.

On the other hand, fixing the machine on the spot may not always be feasible, especially if the bartender does not have the proper training or tools for repairs. Leaving the station is not an option as it neglects the responsibility of ensuring customer service. Continuing to use malfunctioning equipment could lead to safety risks and unsatisfactory service, negatively affecting the establishment's reputation.
