Don't Risk Spoiling Your Leave by Bottle Fatigue" poster
The pattern
This still is filed under Problem-agitate-solve.
Define
Name the problem, make the cost of leaving it felt, then present the way out as relief.
Mechanism
Tension then release. The offer is not an interruption. It is the only door once the cost of staying is clear.
Verdict
The problem is known but not yet urgent
Why it works
It uses humor and cartooning to deliver a strict disciplinary warning without sounding like a lecture from a commanding officer. 'Bottle fatigue' is a clever play on 'battle fatigue', speaking the sailors' language.
Steal this when
You need to deliver a strict warning or policy reminder to a young, rowdy audience without provoking immediate defensiveness.
