A restaurant has reportedly apologised and fired an employee who wrote a racist remark on an Asian woman's receipt.

Cornerstone Cafe NYC worker in New York wrote "Ching Chong" in place of the woman's name, causing outrage on social media.

Ziggy Chau, a friend of the customer's daughter, posted an image of the receipt to Facebook labelling the staff member as "racist" and calling on the community to boycott the restaurant.

"Please boycott this place Cornerstone Cafe NYC until they publicly apologise," she wrote on Facebook.

"Better yet, call them directly and let them know they have a racist staff.

"Racism has no place ANYWHERE. Asian friends----- speak up for ALL... not just when it affects you, please."

Chau also urged the Asian community to share her post "in light of what is happening here in the USA", adding that President Trump has seemingly "made it OK to come out and be blatantly racist",

Chau called the Cornerstone Cafe to complain where the manager, Rocco, initially stood up for his employee suggesting the server must have misheard the customer.

However, Cornerstone Cafe later apologised on social media revealing they sacked the employee.

As manager, I take full responsibility and I humbly ask for forgiveness for all who got offended," Rocco wrote.

"This act is not acceptable and I thank you for bringing it to my attention. This behaviour will not be tolerated," he added.

Despite backlash from reviewers following the incident, Chau wrote on Facebook she does not wish for the restaurant to close down.

"There are many people that are employed by the restaurant whose livelihoods depend on their jobs there and should not suffer because ONE IGNORANT employee thought it was OK to make a racist remark," she wrote.
