Nowadays the NEA are more interested i keeping hygiene as 1st priority but they forgot Lee Kuan Yew's moto, that we have to be courteous citizens.
Most of the hawkers nowadays are rude and unreasonable.
Wen you queried about something, eg. the price or food content, you get shouted instead of proper explanation and the final answer is "you not happy, don't eat lah, who ask you buy from me?".
Grading by NEA should include hawker's attitude and courtesy!
