Yeah. You are absolutely right. What I meant was that if someone wants to use the prepaid taxi, they should avoid listening to the Taxi drivers on the FOB who guide them towards the Platform 4 exit. The taxis, the few present, on platform 4 side may charge higher than the prepaid taxis available on Platform 1 side especially for first time tourists. Anyway, I should not be talking about the costs because I have not used a taxi, prepaid or otherwise, from Madgaon for a long time now. :)
