My Starbucks app was not functioning correctly even after checking my wi-if and app settings and turning each on and off again. Darian, the super polite and cheerful Starbucks associate, did her best to help me and manage a long line of patrons. After a few unsuccessful attempts she offered calling Starbucks to add the stars retroactively. I expressed my disinterest in calling them and she was empathetic and offered me a free drink. This was not necessary and there was no tip option so I figured I'd express my gratitude here. Thank you so much Darian and I hope your boss sees this!
