Platform: INSTAGRAM Author: @pubity --- Caption/Description --- A doctor saved someone’s life… and got a 4 star review. 😭 Dr. Mark Lewis, a cancer specialist, shared a patient review that said “saved my life” but still wasn’t a perfect score, joking that he’s not sure what it takes to earn that fifth star. The post blew up, with other doctors sharing similar stories of life saving care getting average ratings. And the wild part is studies have shown most medical reviews aren’t even based on outcomes, they’re influenced more by things like wait times, parking, or overall experience. So yeah… saving your life might still not be enough for 5 stars. via marklewismd (X) #Pubity #Viral #Health #Funny --- Carousel/Slides (2 items) --- Slide 1 (image): Text: A PATIENT GAVE THIS DOCTOR 4/5 STARS EVEN THOUGH HE SAVED THEIR LIFE Honestly don't know how to earn that 5th star Slide 2 (image): Text: Mark Lewis @marklewismd Honestly don't know how to earn that 5th star ★★★★☆ Dr Lewis saved my life!
