"I said, ‘What?’ He said, ‘I’m paying for this.’ I said, ‘No, you’re not.’ He said, 'Yes, I am,’” Modlin said.
The man paid, and then handed her the receipt for $211, saying, “Merry Christmas!”
“He said, ‘That’s my daughter and wife over there. We just wanted to come out and do something nice for somebody, and we picked you guys,’” Modlin said.
Awaiting a liver transplant for 18 months, Modlin has been in and out of the hospital with liver failure. Her husband, Ray, called the anonymous family "angels of Christmas."
