Something is happening....over a period of about 1 week, two taxi drivers tried to cheat us, possiblity since we are foreign they think we are tourists....it happened so seldom in the past, we were not ready for it. But we argued and the taxi driver immediately gave in both time.
CAUTION: always make sure the meter is turned on when you get in the cab. If not, expect the taxi to request at least a double fare. If it happens, tell your driver that you KNOW that they are cheating. If you decrease the fare by 50% of or more you probably will not get much of an arguement.
