A 70-year-old Domino's delivery driver named Dan is going viral for his thoughtfulness.
The Domino's was out of soda, so Dan went to the grocery store on his own to replace a missing Diet Coke.
The customer was thankful, but bummed he couldn't tip more at the moment. So instead, he started a GoFundMe to help him out.
It's now raised over $29,000.
