‘Karen got decaf for six weeks’: Barista serves Karen customer decaf for six weeks after Karen messes with staff

Staff working in the service industry are often greeted by unruly Karen customers who march in like they own the place, demanding discounts and ordering them around. Often because of poor management, the staff are forced to deal with the impolite attitude quietly inside their heads, as opposed to talking back and standing up for themselves. In this case, OP was working as a barista at a coffee shop where they served such a Karen customer, who happened to be a regular. Karen was manageable up until a certain point when she unleashed all her inner emotional baggage onto a poor new employee who was simply doing their job.

The new employee in question had asked Karen for her ID, since the credit card said that on the back, in the signature panel. Karen reacted by flinging her credit card at the employee, which crossed more than a few boundaries. OP began a campaign that last six weeks, where Karen was continuously served decaf, as opposed to her regular coffee. The rest of the staff joined in, and soon enough, Karen was beginning to feel the effects, or rather the lack thereof, of the decaf coffee she was given.
