Singaporean Lee Ah Loo, 66, was also charged in court on Wednesday with harassment.
Lee is accused of uttering vulgarities at a National Environment Agency (NEA) enforcement officer on two separate occasions on May 2 and April 26 at Beo Crescent Market.
Lee told the court that he would not be pleading guilty, noting that the officer had scolded him first. He did not elaborate on how the dispute arose.
