Who knew changing coffee could cause such carnage?
A 19-year-old summer temp exacted sweet revenge on a clique of hostile older coworkers by secretly hijacking the office coffee supply for two chaotic weeks. Assigned the daily ritual of buying beans and loading the machine, he faced constant rudeness and isolation from day one.
What makes the story more complicated is the physical fallout—decaf withdrawal headaches in week one, followed by hyperactive jitters and unexpected digestive disasters from ultra-strong brew in week two. The office transformed into a caffeine-fueled battlefield.

The temp role landed him in a toxic office dominated by unfriendly colleagues.


The payback unfolded quietly over two weeks with swapped coffee types.


Workplace pranks like coffee tampering sit at the crossroads of harmless mischief and reckless endangerment. The temp’s two-week experiment masterfully weaponized a daily ritual against chronic hostility, delivering poetic justice without fingerprints or confrontation.
Skeptics highlight genuine medical risks—sudden caffeine withdrawal triggers migraines, irritability, and fatigue mimicking illness, while a jolt from ultra-potent beans like “Lava Java” can spike heart rates, induce palpitations, or exacerbate IBS in sensitive individuals. In addition, the edit’s revelation of digestive chaos underscores how bodily betrayal amplifies humiliation. Yet the short timeframe and absence of reported hospitalizations kept it in prank territory rather than lawsuit bait.
From an organizational lens, bullying often festers unchecked in hierarchical settings, especially toward temps seen as disposable. This stunt flipped the script, forcing the clique to experience vulnerability they’d inflicted. “When formal channels fail, anonymous acts of petty rebellion can recalibrate power and deter future abuse,” argues Dr. Tessa West, NYU social psychologist and author of Jerks at Work (2024 TED Talk). She cautions, however, that escalation-prone targets might retaliate disproportionately.
Ethically, the prank scores points for proportionality—the suffering mirrored the emotional toll of isolation, not exceeding it. Socially, it joins a pantheon of underdog legends where the little guy brews chaos to level the playing field. The real genius? It ended when the temp presumably left, leaving the office none the wiser and forever paranoid about their next cup.
Here’s the comments of Reddit users:
