IRVINE (CBS) — A cashier at a fast food restaurant in Irvine has been fired after insulting two Asian customers.

KNX 1070’s Mike Landa reports it all stems from two racially-charged names that were printed on a receipt.

The cashier reportedly typed the names “Ching” and “Chong” on the receipt of two customers who said they were regulars at the Chick-fil-A restaurant on Jamboree Road.

She was fired soon after the incident was reported, officials said.

A company spokesman called the incident “immature behavior, failed judgment, and human error”.

Chick-fil-A has recently come under fire from gay rights activists for its support of traditional marriage.

The chain’s political leanings, however, have yet to weaken demand for its food as evidenced in September when crowds flocked to the grand opening of its newest store in Hollywood.
