Pity her... Have to face such idiots while doing her job.

Pakai seragam pn takde org nak naik teksi.

WEAR DECENT CLOTHING
E.g. long trousers, collared tees, and close-toed shoes.

This lady should follow Grab's community guideline. What is considered as decent here is not well defined. Anyway, it's up to the passengers and grab to comment on her attire, not the taxi driver. The taxi driver's act here is an obstruction of people doing their work and harassment.
