When a stressed-out mom rolled up to a McDonald's drive-thru to purchase a meal for her children, she realized with dismay on making her order that she'd left her purse at home. But the teenage server at the window didn't send her away.

Wyatt Jones said he'd happily pay for the meal.

Brittany Reed was more than grateful. It had already been a long day at soccer practice with her 4- and 7-year-old.

Later that night, purse in tow, Brittany drove back to the McDonald's to give Wyatt his money back. But the Waynesville, Ohio local insisted the meal was on him.

Brittany wrote in a Facebook post, "I just want his parents to know how KIND & COMPASSIONATE your son was tonight! He made this stressed out momma pause for a moment and realize this is exactly what we parents are trying to do, raise great humans," she explained. "Wyatt, do not let this world change your kind heart young man for its people like YOU that will change this world for the better!"

Wyatt had shown Brittany such kindness. How to thank him even more?

On hearing that he was saving up to buy a car, Brittany began a GoFundMe campaign on his behalf. As of October 1, she's raised nearly $32,000 for him. How's that for a gratuity?
