Denise Wilson, a spokeswoman for the company, apologized to Francisco Perez after his receipt from the Sacramento location bore a profane four-letter word beginning with "f," KCRA-TV, Sacramento, reported Thursday.

"The franchisee has taken immediate corrective action and both the manager and employee are being terminated. The franchisee will be reaching out to the guest directly." Perez said he does not know why the message was written on his receipt after he ordered Double Whopper with cheese, onion rings and a small drink. The customer said he will not be taking advantage of free food vouchers from Burger King as he does not plan to return to the restaurant. "I'm embarrassed," he said. "It's humiliating."
