More courtesy" poster
The pattern
This still is filed under Public health warning.
Define
A warning designed to change a health behavior (stop, screen, stay home), not to sell a brand.
Mechanism
Fear with a next step. The threat is specific. The action is doable today. Fear without an action is cruelty.
Verdict
The risk is real and the action is clear. Official or civic voices help.
Why it works
Humor and exaggerated proportions highlight the power dynamic between bureaucrats and citizens, making the plea for courtesy feel necessary and relatable.
Steal this when
You want to criticize a common negative behavior without being overly aggressive, using humor to soften the blow.
