Mr. Smith can file a complaint with the U.S. Equal Employment Opportunity Commission (EEOC) since he faced discrimination based on his race. The Civil Rights Act of 1964 prohibits discrimination in public accommodations, including restaurants, based on race, color, religion, or national origin. The EEOC is the federal agency that investigates employment discrimination complaints, including those related to public accommodations.
Mr. Smith can contact the EEOC and file a complaint against the restaurant for violating his civil rights. The EEOC will investigate the matter and may take legal action against the restaurant if they find evidence of discrimination. It is important to note that Mr. Smith can also file a lawsuit against the restaurant directly, but it may be advisable to consult with an attorney before doing so.
