Reacting to Serbian Novak Djokovic's first-round exit from the Rio Olympics, a user tweeted, "Anyone that says #Olympics doesn't mean anything to tennis players, hope you watched @DjokerNole vs @delpotrojuan both in tears at the end". Another tweet read, "In the morning, Juan Martin del Potro was stuck in an elevator for 40 minutes. In evening, he beat Djokovic."
