Danielle Franzoni, a server in Alpena, Michigan, received the tip of the decade this week.
Franzoni waited on a couple at the restaurant where she works during the final days of 2019.
Their bill was $23, but the generous couple tipped a festive $2,020.
According to CNN, the anonymous couple wrote "Happy New Year, 2020 Tip Challenge" on the bill.
Franzoni told the Alpena Times "Things like this don't happen to people like me".
Franzoni said she'd had a difficult year and had moved to Alpena to "start over" after surviving addiction and homelessness.
"I"m gonna build a future because of this. My kids have a future, and I have a home. It's a really big deal."
