BANGKOK (Thomson Reuters Foundation) - When Jay Fai, a 70-year-old street food seller in Bangkok known for her crab omelettes, won a Michelin star last year at the launch of the city’s first restaurant guide, few locals were surprised.

“Auntie Fai” is as renowned for the ski goggles she wears to protect her eyes from hot oil splashing, as she is for her thick crab curry and dry congee that customers, including many who drive up in luxury cars, swear by.

But the afterglow from the global adulation was short-lived, as city officials soon resumed a drive to “return the pavement to pedestrians” evicting hundreds of vendors selling food, clothing and trinkets, for greater “order and hygiene”.

Earlier this month, hundreds of hawkers marched to city hall following a daytime ban on vending on the sidewalks of Khao San road, a favorite haunt of backpackers.

What began as disparate protests by vendors facing marching orders has now morphed into an organized citywide movement that has also won support from academics and other public figures against the perceived heavy-handedness of officials.
