A
It creates confusion
-
B
A backed-up server is more confident refusing service, and the team handles difficult patrons more safely
-
C
It reduces compliance
-
D
Servers should work in isolation
Why this is the answer
Cross-training staff to recognize and support each other's responsible-service decisions helps because a server who knows colleagues and management will back their refusal is more confident in making the right call, and the team can respond to difficult patrons more safely together. When everyone understands the standards and supports one another, a single server is never left alone to face a confrontation or a tough judgment. This mutual support strengthens compliance and safety. Managers foster it by training the whole team and consistently backing staff who make responsible decisions.
