The anonymous customers asked for the grumpiest waitress on duty, saying they wanted to make her smile.
When the hostess told the men there was no one grumpy on staff they gave them Abigail Sailors, a woman they said was the happiest person there.
At the end of the meal Abigail was thrilled to discover a crisp $100 bill as a tip.
But then she couldn’t believe it when she found another $6,000 in checks on the table.
Sailors is a favorite at the restaurant where regulars know her story.
Abigail was a foster child after her parents were badly hurt in a car accident. Sailor and her five brothers and sisters were trapped in an abusive foster home before she and a sisters moved back in with her father.
Not long after, her dad was arrested for abuse.
Abigail then found a foster family she says saved her. "I don’t know how I would have turned out if I didn’t have them, they shaped the person I am today," she proclaimed.
But now Abigail is working her way toward a degree in youth ministry and psychology at Trinity Bible College in North Dakota.
When she told the men she had put classes on hold due to a lack of money, they stepped up.
One left the $100 and the other left a check for $5,000 for tuition and another $1,000 for whatever she might need.
"I couldn’t believe it," Abigail told the Journalstar.com "I tried to thank them, and they said, 'Thank God.'"
