Joan Rivers / Los Angeles Times (August 7, 2012)

Joan Rivers chained herself to a shopping cart at a Burbank Costco store on Tuesday in an apparent publicity stunt before leaving when police arrived at the scene, a city spokesman said.

Rivers has been saying that Costco has refused to sell her new book, "I Hate Everyone ... Starting with Me," which has made the New York Times bestseller list.

She was talking about her book as she was chained Tuesday afternoon to the shopping cart with a film crew in tow, said Burbank spokesman Drew Sugars.

"She had a whole entourage," Sugars told The Times. "Sounds like a staged media event."

Rivers refused to leave until Burbank Police Department patrol units and a sergeant arrived. No citations were issued, Sugars said, and no arrests were made.
