"It's been amazing and it's just been typical of the support we've gotten since we started this journey about 2 1/2 years ago," said Lance Fleming.
Not only was it a surprise to Fleming, it was beyond touching.
"I think it's a testament to how he lived," he said of his 10-year-old son.
People were willing to stand in a crowded line for their meal, and even more surprising, they didn't seem to mind.
It's been five months since Rex died from brain cancer.
Since then, his family has set up a foundation in his name to raise money for iPods and other items that will help kids battling cancer.
You may think games like Angry Birds are just for fun, but if you're in a hospital bed for days at a time, it can mean a lot more.
"So we wanted to give those kids that can't afford it an avenue to have that," said Fleming.
3-year-old Callie Cochran can vouch for that.
She's now cancer free and willing to pour a few glasses of lemonade to help with the cause.
"For the sick kids in the hospital," she said.
Rex wasn't only a friend, he was an inspiration for Callie's parents.
"It was just comforting because people were always praying and caring, but to know that somebody had walked those shoes and had come through the other side of it was amazing," said Courtney Cochran.
They're not the only ones touched by Rex's life.
"He's my hero and he will be forever," said Fleming.
"It's been a blessing to our entire family to be united in that and in him and the blessing that his life was," said Meg Knight, who didn't know Rex personally, but was touched by his story.
All you have to do is take a look around this room to know his name certainly won't be forgotten.
