ALPENA, MI – A Northern Michigan waitress has an extra $2,020 in her bank account after one generous tip this week.

The customer is calling it the “2020 Tip Challenge,” which they wrote on the receipt above the tip line after dining at Thunder Bay River Restaurant on Sunday, Dec. 29, The Alpena News reports. Their bill was $23.33.

Server Danielle Franzoni couldn’t believe it was real, but her manager – who was also shocked by the generosity – assured her it was legitimate, the report said.

After Franzoni’s shift ended, she went out to eat and tipped her server $20.20 as a small way to pay it forward – and a much more feasible way for most people to get in on the “2020 Tip Challenge.”
