A San Francisco strip club is suing Oracle, saying the software giant refuses to pay a whopping $33,540 tab racked up by one of its employees.

The unpaid tab dates back to last year during the Oracle Open World Conference, held each year in San Francisco. According to the New Century Theater, an employee of Oracle's Spanish subsidiary named Jose Manuel Gomez Sanchez and his guests incurred the charges in the early morning hours of October 2, 2012, and again during a return visit, two days later, on the conference's closing day.

Oracle declined to comment on this story. The suit was filed earlier this month in San Francisco county court, but was first reported yesterday by the San Francisco Chronicle.

According to credit card slips filed in court, Sanchez spent thousands of dollars on "Club Dollars," used to pay for lap dances between 1:18 a.m. and 5:26 a.m. (three hours before Oracle CEO Larry Ellison took to the stage to "provide insight into Oracle’s Oracle Cloud Social Services strategy"). Sanchez's total bill for the night? $16,490, the strip club says.

The New Century Theater, a club in San Francisco's Tenderloin neighborhood, does not serve alcohol.

Sanchez allegedly put the charges on his Oracle corporate American Express card. But Oracle refused to pay AmEx two months later, leaving the strip club empty-handed.
