Sam has been your go-to barista at the local coffee shop for the past two years, memorizing your intricate coffee order and always throwing in a personalized joke to start your day off right. Recently, however, you've begun to notice peculiarities in Sam's behavior. His recall of your order has been flawless, to the point where you question how he remembers every single detail so perfectly. Yesterday, when he greeted you, the phrase 'your daily concoction awaits, as you preordered' felt oddly rehearsed, and when you mentioned an off-handed comment from a past visit, Sam responded with an unsettlingly precise recollection of the event. His gaze was vacant, and it sent a chill down your spine.
