The New Jersey waitress who claimed she was denied a tip because of her sexual orientation may have forged the receipt.

Dayna Morales, a former Marine, claims she was stiffed out of a tip earlier this month. Instead, the customers left a note telling the waitress they did not agree with her lifestyle.  

Morales, a server at Gallop Asian Bistro in Bridgewater, posted a photo on social media earlier this month, showing the bill with a line crossed through the space for a tip. The photo of the receipt showed someone had written, "I'm sorry but I cannot tip because I do not agree with your lifestyle."

However, according to NBC News, the family, who said they were the patrons served by Morales claim they didn't write the note and actually left a tip for the waitress.

The couple, who have asked to remain unidentified, said they were upset when they saw media outlets reporting on the story, which they called false.

The couple exclusively showed NBC a copy of their credit card statement as proof. The statement showed that they were charged for the bill plus a tip, totaling $111.55, which is an $18 tip. Previous reports showed that the posted bill was $93.55 total.

The couple said they believed their receipt was used for a hoax. The wife said she is left-handed and "could not have made the slash in the tip line." The husband said both he and his wife worked in the food business and believe in the value of tipping restaurant workers.

"We've never not left a tip when someone gave good service, and we would never leave a note like that," the wife said.

The family also stated they did not vote for Governor Chris Christie because he does not support gay marriage. The couple, who are calling Morales' actions "dishonorable," submitted a copy of their credit card statement to support their claims.

"I said, 'oh my god,' she's doctored up our check," the wife told NBC4.

Morales has reportedly been receiving tips from people around the world and has been donating some of the money to the Wounded Warrior Project.

"I just felt like people have a right to know that, it's fine of people want to donate to her or to the Wounded Warriors, but they're doing it under a false pretense," the wife said.

The restaurant told NBC that they're opening an internal investigation.
