Today in Gulf News: One man fined Dhs. 2000 for plying his car as illegal taxi by RTA. He was taking his friend to drop him somewhere in his way to work. He showed the officials all evidences but failed to convince them. He was reffered to police but no one helped him. He then walked into RTA office and showed his one year old picture showing both the friends at some picnic spot with families but he was shown his way out by the security people and officials told him to go to court.
This is one of lot of stories of expats living in Dubai. They dont have any option if they are fined whether they are right or wrong. They have to pay it.
Cops and officials are final authority here. If they say it is day it is day dont worry even if they are claiming it in the night. You have to say yes.
