Cassandra Walker, the Dairy Queen employee who made a viral marijuana-themed cake, said she was fired on her birthday for the mix-up.

INSIDER previously reported on the Georgia woman who ordered a "Moana" birthday cake but was misheard by a Dairy Queen employee who thought she said "marijuana."

Walker told USA Today that her manager misheard the order and told her it was OK to make a marijuana-themed cake.

A representative from the Milledgeville Dairy Queen previously characterized the birthday-cake mix-up as a "simple misunderstanding."

A Dairy Queen representative confirmed to INSIDER that Walker was terminated and was later offered her job back but declined.

The Dairy Queen employee who made a viral marijuana-themed cake said she was fired on her birthday for the mix-up.

Cassandra Walker, the Georgia woman who made the cake, told USA Today that it was her manager who misheard the customer's cake order over the phone, mistaking "Moana" for "marijuana."

The ice-cream cake, which said "Happy 25th birthday Kensli," was decorated with green and white frosting and featured a large cannabis leaf next to what appeared to be a "My Little Pony" character with red eyes smoking a joint.

Walker said her manager told her it was OK to make the marijuana-themed cake.

"The manager stood behind me while I pulled the images off the internet," Walker told USA Today. "She walked by as I decorated the cake. As I boxed the cake up, she was the one who walked it up to the front."

Walker said Dairy Queen fired her for the mistake on July 8, her birthday. A Dairy Queen representative confirmed to INSIDER that she was terminated and was later offered her job back but declined.

Walker said she turned down the offer because she wasn't pleased with the way Dairy Queen handled the situation.

"To be at this job for almost a year and not have a write-up, not be in trouble, and to just be let go because of mistake, it's not funny to me," she told USA Today.

The recipient of the marijuana-themed birthday cake was Kensli Taylor Davis, 25, of Milledgeville.

Davis is a huge fan of "Moana," a popular animated 2016 Disney film about a Polynesian princess. For Davis' 25th birthday, Davis' mother decided to get her a cake based on the film.

"So my mama called and ordered me a cake telling them how much I loved Moana. (Because really I do)," Davis wrote in a Facebook post with a picture of the cake on July 2. "Well needless to say these people thought she said marijuana."

"My sister picked it up and FaceTimed my mama the minute she saw it," Davis told INSIDER. "We all died of laughter because it was obviously an honest mistake."

Davis said that she didn't think the cake would go viral and that she was "blown away" by the response on social media. The Facebook post had more than 14,000 shares and 14,000 reactions on Friday.

"I was just sharing with my Facebook friends how funny the mix-up was, and it just went from there," Davis said. "I'm just a 25-year-old who loves Disney movies who just found the good in a bad situation."

While many people on social media found the mix-up humorous, Walker said she didn't share their sentiment.

"This is back-to-school time. I have two little girls here," Walker told USA Today. "I have a car that needs fixing. It's not funny to me."

Walker said she was made aware of her firing by Al Autry, an owner of the Milledgeville Dairy Queen who previously told INSIDER that the mix-up was a "simple misunderstanding."

"Our cake decorator designed a cake based on what she thought she heard the customer order," Autry said in an email to INSIDER.

"When the customer picked it up and said it was not what she ordered, we immediately apologized for the error and offered to redesign it the way she originally intended," Autry continued. "The customer said it was fine, paid for the cake, and left."
