Singapore "news"

I heard some interesting "news" from my friend who comes from Singapore. She told me that English is very important and useful language in the world; therefore, even fishmonger can speak it fluently in Singapore market. One day, while she passing by the vendor and then she heard the fishmonger was very angry at the customer's deeds and warning the customer: "don't play play with my fish, quick buy buy and quick go." Well....it sounds like Chinese English, but few customers could deny they understanding it. Just a joke~
