After confirming the validity of the 609 percent tip with Drummond, Diaz, who initially was unaware that she was serving an NBA athlete, struggled to find the appropriate way to show her gratitude. “I was so nervous that if I was too excited other customers might recognize him and start bothering him and then he’d get upset and take the tip back,” Diaz said with a laugh. “But looking back on it the next day, I really felt like I didn’t express enough just how appreciative I was, so I decided to post about it on Instagram in hopes that he’d see it.”
