In a world filled with franchised restaurants, coffee shops, supermarkets, and more, you'd think that most everyone would understand that inevitably someone who works at one chain coffee shop location could quite possibly wind up visiting another one as a customer when they're off work and free to enjoy the world as they see fit. Some people — namely, the Karens who walk among us — get confused when this happens, but rather than admit to making a mistake, they just double down.
Redditor u/flamealee posted to the popular subreddit r/IDontWorkHereLady to share a story from their days working at a popular Canadian coffee shop franchise as a teenager. When OP said they once visited a different franchise location while waiting for their grandfather at a doctor's appointment, a customer who recognized OP from the actual coffee shop location they work at entered and attempted to get OP's attention, figuring they must also work there, too. Things got intense as the wicked customer apparently slapped OP's drink out of their hand and yelled at them to help her, only for the store's actual employees to tell her off.
A few days later, OP says they were working at their actual job when this very same customer showed up. This time, OP's manager was there to tell the customer off — Karen walked out empty-handed that day.
