I saw a posting on the Taxi Driver Facebook page and was quite disturbed by a comment made by someone named Wan Edison.
In his posting, he challenged everyone of his intention to book a grabcar and thereafter upon reaching the destination, refuses to pay for the agreed upon fare.
I think such actions are rather childish and also damaging the reputation of taxi drivers. The grabcar driver who will be picking him up may just be earning an honest living like everyone else. There is no reason why he has to resort to such childish measures.
I have attached screenshot of his posting. U may visit the Facebook page to view the posting made by him.
