LITTLE ELM -- Kasey Simmons is on a mission it to make you smile.
"It's selfish really," Simmons said. "When people smile, I feel better. It lightens my world."
The 32-year-old is a server at Applebee's in Little Elm. On Tuesday, he got one of the largest tips on one of the smallest checks of his career.
"They ordered the cheapest thing on the menu of flavored water -- it was $0.37," Simmons said, "but my tip was about 50,000-percent."
The diners left Simmons $500, along with a letter written on an Applebee's napkin explaining why.
The day before, Simmons was at the Kroger grocery store when he saw a woman who looked upset. Simmons said he wants to help everyone -- including strangers -- so he approached the woman and offered to pay for her groceries.
"I insisted," Simmons said. "It was only $17, but it's not about the money -- it's about showing someone you care."
After reading the napkin/letter, Simmons learned that woman at Kroger was mourning the three-year anniversary of her husband's death. The $500 tip and the letter were written by the woman's daughter, who wanted to thank the man who showed her mother kindness when he could've easily walked away.
"I had no idea that was going on, but I knew something was making her sad," Simmons said.
Simmons said he's happy to make anyone happy, but he has one wish: He'd like to meet the family to say thank you, face to face.
