"There's no home in my restaurant for hatred, bigotry, racism, homophobia, discrimination," Orosco told NJ.com. "If anyone feels the same way, don't come back."
Orosco said he came to the U.S. in 1991 with his parents. He worked his way up from dishwasher and has owned the restaurant for 13 years.
Orosco said the server is of Spanish descent and was born in America. He said he believes the note was left after the multilingual employee started speaking Spanish to another employee.
His post had a message for the anonymous diners:
“Please do not come back.”
