Getting chewed out by your boss in front of a customer is humiliating enough. But when the “lesson” makes no sense? That’s when petty revenge starts brewing, literally.
One diner worker was publicly scolded by their manager for serving a trucker a regular 12-ounce coffee in a to-go cup because, apparently, when a customer says “big coffee,” staff were supposed to magically know they meant a 30-ounce soda cup filled with hot java. The rule had never existed before, but the manager threw them under the bus anyway.
So the employee decided to follow the new “policy” to the letter, every single time. The result? A coffee maker that never stopped running, endless refills, and a whole lot of free upgrades customers didn’t even ask for.
The employee explained that the diner only offered one size of to-go coffee—12 ounces









Public reprimands often backfire. According to the Harvard Business Review, employees who feel humiliated in front of peers or customers are 50% more likely to disengage from their jobs and look for ways to retaliate, sometimes subtly, sometimes dramatically.
Dr. Tasha Eurich, organizational psychologist and author of Insight, notes: “Leaders who embarrass employees publicly destroy trust instantly. Respect is the currency of management, and when it’s squandered, people stop working with you; they start working around you.”
Coffee may seem trivial, but the diner’s situation highlights a bigger issue: micromanagement mixed with inconsistency.
Studies from Gallup show that disengaged employees cost U.S. businesses up to $550 billion annually in lost productivity. And disengagement doesn’t always look like slacking; it can be subtle sabotage, like handing out three times as much product without charging more.
The healthier approach? Private feedback, clear systems, and empowering employees to solve customer concerns without arbitrary new “rules.” As HR expert Sharlyn Lauby points out, “Employees need confidence in the consistency of policies. If rules change depending on the customer, resentment grows.”
Here’s what people had to say to OP:
Redditors said the real issue was the manager humiliating staff in front of customers, something they’d stopped patronizing businesses for


This group joked that now customers would expect “Pat’s Big Cup Special” forever, just like other workers who secretly gave discounts out of spite


Former service workers shared similar tales of bosses making up contradictory rules, leaving staff to pick which “truth” to follow






A trucker admitted he solved the “large coffee” problem years ago by simply bringing a thermos



Do you think the worker’s compliance was fair justice, or did they cross the line from petty to reckless? And if you were in that diner, would you have taken the free 30oz cup, or pointed out the absurdity?
