The Pulp Fiction star reportedly had a representative call to book a table at the fast food chain on Friday night, according to the Daily Mail.
However, Travolta was turned down by the individual who took the call.
"To me, customers are customers, no matter who they are. It doesn't make a difference if someone is famous," the worker said.
The staff member continued: "The lady who called didn't give me her name, she just said it will be for a Mr Travolta.
"That threw me a little bit. I thought it might be a load of nonsense, but she seemed pretty serious."
On Thursday, a spokesperson for KFC expressed regret for failing to accommodate the star.
"In hindsight, of course, we would have reserved a table for him. It's not every day you get a Hollywood star eating in your restaurant," said the rep.
Last month, Travolta's vintage Mercedes-Benz 280SL was stolen in Santa Monica, after the actor apparently parked the vehicle on the street before visiting a Jaguar car dealership.
The police have since sought help from the public, offering a reward for information leading to the return of the actor's stolen car.
