A local Chili's restaurant in Midvale, Utah, might have made the grave mistake of "breaking" one little girl's cheeseburger by cutting it in half, but the waitress, manager and line cooks more than made up for it Sunday when they presented her with a brand new "fixed" one.

Seven-year-old Arianna Hill is autistic and she loves cheeseburgers. But apparently, ones that are cut in half just won't do.

"We just decided we were going to get some lunch before we were taking her to see the Easter bunny," Arianna's older sister, Anna MacLean, 25, told ABCNews.com. "She usually does OK in restaurants. It seemed to be going pretty well. She wasn't too overstimulated. She was really enthusiastic before we were even able to put our drinks orders in. She told the waitress, 'I'll have my cheeseburger.'"

However, when Arianna's burger was delivered to the table, MacLean noticed that Arianna wasn't touching it, but instead only eating her french fries.

"Her verbal skills aren't the best, but she can communicate basic things," MacLean said. "I asked why she wasn't eating and she said, 'I don't want it. It's broken.' She said, 'I need one that's fixed.'"

MacLean loves spending time with Arianna, but is always prepared to come across someone who might not be as understanding of her special needs. Fortunately, the restaurant didn't skip a beat in correcting the broken burger and their compassionate actions have now gone viral.

"Our waitress came back over and I felt bad. I don't really expect people to understand these special requests, so I just told her to add a new burger to our bill," said MacLean. "I just told her to charge it to us and she said, 'No way.' She was just so sweet and played along with Arianna."

The Chili's server, Lauren Wells, didn't hesitate before leaning down to personally apologize for the broken burger and assured Arianna she would bring her a brand new fixed one.

"The manager came over and did the same thing. It was really a big deal. The line cooks even got involved," MacLean said. "When she brought it back out, Arianna said 'Oh, thank you! You brought me a fixed cheeseburger.' She sat there and looked at it and said 'Oh I missed you,' and kissed it over and over again."

MacLean was so touched by the staff's compassion and understanding that something as minor as a cut-in-half cheeseburger would be enough to ruin Arianna's whole day that she snapped a photo of Arianna giving the cheeseburger a kiss and uploaded it to Facebook along with a brief description of how well the restaurant handled the situation.

Before MacLean knew it, the "broken cheeseburger" photo had more than 100,000 "likes" on the social media site, a number that continues to rise rapidly. At the time of this writing, the post had more than 220,000 "likes" and 10,000 comments.

"It's just touching," said Harrison Dixson, the Chili's general manager. "I had no idea. I looked at it this morning and it had a couple thousand likes. I thought someone would say, 'Hey, good job Midvale. But I'm talking to 'Good Morning America.' This is just unbelievable."

Dixson said he's gotten calls from people all across the country, including the president of Autism Speaks, an autism advocacy organization, thanking him for the way his manager, Brad Cattermole, and server, Lauren Wells, interacted with Arianna.

"I can't tell you how proud I am of those two. I've been with this company for 13 years and I've never been as proud as I am today," said Dixson.

"It turned out great and this turned into something way bigger than anything I ever imaged," MacLean said. "The comments on the post just bring awareness to people. This is Arianna's story. And this is Lauren's story, and the manager. They are a true inspiration."
