A couple who dined at a New Jersey restaurant left a hateful message for their multilingual Spanish server scrawled on the back of their bill saying, “Don’t Tip Immigrants!!!,” according to the eatery’s owner.

Santiago Orosco, owner of the Under the Moon Cafe in the Burlington County city of Bordentown, recounted the incident over the weekend in a lengthy Facebook post.

Orosco claimed that on Thursday, a couple “in their mid to late 40’s” dined at the Argentinian eatery and even “raved about the food, the décor, and the service.”

“Upon arrival they seemed very excited about dining at Under the Moon, complementing the ambiance, as well as all the recommendations that our server had made,” Orosco wrote.

After the couple’s meal, the server “grabbed the check from the table, told the customers, goodnight and thanked them as they were leaving,” according to Orosco.

“While our server was closing out for the evening and reconciling sales receipts, she noticed that these customers had written a note on the back of their bill stating, ‘DON’T TIP IMMIGRANTS,’” Orosco said. “I can only assume that they heard our American multi-lingual server speak Spanish to another employee.”

Orosco went on to say that he is “utterly shocked at this blatant ignorance.”

The restaurant owner who calls himself “a very proud immigrant” has owned the Under the Moon Cafe for 13 years and said that “we are extremely proud to be part of the community.”

“I came to this wonderful country for a better future, which, with a lot of sacrifice, heartache, pain and sweat I have accomplished,” he said. “My family has tirelessly worked to create a great life and I owe it to this country and all its opportunity (America has always been great!!!).”

Orosco added: “Immigration and cultural blending are what created this special country; I truly believe that immigrants are key contributors to our society.”

“Also, I am gay, at Under the Moon we accept all people but not ignorance and discrimination,” said Orosco.

In a message to the hateful diners, Orosco wrote: “PLEASE DO NOT COME BACK!!!”

He noted that the patrons’ server “who helped create an excellent experience for you, who you discriminated against with written ignorance and no tip, is not an immigrant, she is of Spanish descent, born in America and is multi-lingual.”

The topic of immigration has been at the forefront of a national political debate.
