Dilarang Melatak Kenderaan??

FL found this sign somewhere near his office and decided to take a picture for me to see. Dilarang Melatak kenderaan?? hehe.. It should be an E instead of A la.. I wonder the person that made this sign noticed the mistake or not. Did he notice and decided to ignore it (cos if redo need extra money mar.. :p, just simple cross the A out and replace with an E lar, save cost mar. hehe..), or he didn't even realize the mistake?
