Oliver has been your trusted barista for years, known for his remarkable memory and ability to whip up your complex coffee order without a hitch. However, lately, you've sensed an unsettling shift in his demeanor.

This morning, as you walked up to the counter, his greeting felt off, as if he had rehearsed it rather than genuinely recognized you as a familiar face.
