A massage parlour and a car wash outlet in the Sunway Mentari suburb of Kuala Lumpur, Malaysia, engaged in a flourishing joint venture until it was disrupted by police last week. After nine car washes, customers received a free detailing – but not of the car.

“To get the extra ‘offer’, customers must send their cars for washing nine times within a certain period. The tenth car wash will entitle them to free sex,” Emmi Shah Fadhil, officer-in-charge of the local Crime Prevention Division told the Malay Mail.

Car-less customers, or those who did not want to wait for nine car washes for free sex could pay between 130 and 180 Malaysian ringgit ($42 and $58) for immediate gratification.

A raid of the premises led to the arrest of four men, none of them customers, and “nine Vietnamese women, believed to be prostitutes and GROs, aged between 18 and 28,” says the paper. A report by the Malaysia Chronicle says that the raid netted evidence in form of “several condoms stashed inside a microwave.”

According to a source familiar with Malaysia, GRO stands for “Guest Relations Officer,” and usually applies to women employed by night clubs. PC speak has reached Malaysia, where GRO takes the place of WG, or working girl. Just in case you wanted to know.

The car wash connection was only revealed after loyalty cards were found on several customers (who were not arrested.)

In a blatant act of discrimination, the operation “only allowed patrons of a certain ethnicity to enter,” says the politically correct Malaysia Chronicle. Further research revealed that the services were only available to Chinese, apparently in an effort of not to upset the predominantly Muslim indigenous population.
