A teenager is receiving many happy returns after turning in an envelope she found stuffed with $100 bills.
Kayla Blackmon was sweeping the dining room floor after a rush of customers last week at Freddy's Frozen Custard & Steakburgers in San Antonio.
She found the envelope on the floor with $1,600 inside.
The 17-year-old turned it over to restaurant managers who then checked video to determine which customer may have dropped it.
Soon after a man walked in who "looked really nervous." He had intended to use the money for a Christmas vacation.
Blackmon told the San Antonio Express-News on Thursday that the customer expressed his gratitude by giving her $100.
The restaurant owner, meanwhile, gave her a $100 gift card. She also was chosen employee of the month.
