At the Sweet Snacks Cafe, Pinkie Pie prides herself on making the diner the highest-rated diner in Canterlot, having a consistent five-star rating and no bad reviews on the Screech mobile app. Pinkie's service to the customers earns the diner more five-star ratings on Screech. When she serves coffee to a middle-aged patron reading a newspaper and persistently urges her to leave a review on Screech, she gives a four-star rating instead of five, breaking the diner's five-star streak as well as Pinkie's spirits. 

Determined to earn that last star, Pinkie Pie keeps serving the woman more food, but the woman gets annoyed by Pinkie's constant distractions. Frustrated, Pinkie finally decides to leave the woman alone. She changes her four-star rating to five stars, saying she just wanted peace and quiet to read her newspaper.
