I had to include this sign from a restaurant in Shanghai, as reported by Xinhua, the Chinese state-owned news service. All part of China's efforts to be a more rule-by-law country, I guess. Thanks to CSR Asia for pointing it out.
“Zapata’s Mexican Cantina does not sponsor prostitutes at our establishment. If you are prostitute please refrain from entering our garden or restaurant. If you are unsure whether or not you are a prostitute, please ask one of our friendly security guards to sort it out for you. Thanks.”
