SYDNEY- Paris Hilton may be the poster girl for marathon shopping sprees, but the hotel heiress seemed to have somehow misplaced her gold cards in Sydney, where she left a cafe without paying her bill.

The staff at Sloanes Cafe in the trendy Paddington shopping district were left scratching their heads when Hilton walked out without paying a 9.80-dollar (7.70 US) drinks tab, the Sydney Morning Herald reported Monday.

"She's got bucketloads of money and she didn't pay for her drinks," waitress Jo Pfahl told the paper.

Hilton, in Australia to help promote a new beer, stopped at the cafe on Sunday with her friend Kim Kardashian.

While one of Hilton's publicists had ordered and paid for two burgers, a mineral water and a frappe were also requested and duly provided.

The paper said Hilton barely nibbled her burger and then left to continue shopping without paying for the drinks.

"(Hilton) had a little chat with a waiter up front, then they all got up and walked out without paying," Pfahl said.

The newspaper reported Hilton had planned to celebrate New Year's Eve with Sam Branson, son of Virgin brand mogul Sir Richard Branson, on Sydney Harbour.
