A waitress who was given thousands of dollars in donations after she posted a photo of a receipt which she claimed proved that a family had declined to tip her because she is gay, has come under fire from many who have questioned why the money was not donated to charity, as she promised.

New Jersey restaurant the Gallop Asian Bistro last week said it will investigate the case of a lesbian waitress who said she was denied a tip by a family who said they did not agree with her “lifestyle”, after the family denied the allegations.

Dayna Morales, a gay former Marine, allegedly received a note which read: ”I’m sorry but I cannot tip because I don’t agree with your lifestyle & how you live your life.”

However, NBC 4 New York reported that the family to whom the bill belonged contacted the network after the story broke , denying they had any part in writing the abusive message. According to the report, the family had shown proof, in the form of a credit card bill, that they did tip Morales, and they said they note that she posted online was a hoax.

Morales denied that she wrote the note.

The restaurant on Tuesday posted a message on its Facebook wall saying Morales had been suspended pending an investigation into the allegations that she made the whole thing up.

Since then, a Pentagon source told WNBC that she had been dishonourably discharged from the Marines after she failed to turn up to drills, and former colleagues have spoken out to say that she has a history of lying.

Also, many have questioned why she has not donated the thousands of dollars, the majority of which was given via PayPal, to Wounded Warriors, the charity which she pledged to donate all but the value of a tip to.

A report by the Bridgewater Patch claims that the charity said it was not able to verify that a donation was made by Morales.

Social media users posting on the Facebook page of the restaurant, have criticised the waitress under the belief that the incident never took place, and that she has also failed to donate the money. Some have gone so far as to say that she should be prosecuted by the state for her actions.
