Boarded Batamfast ferry from Singapore Cruise Center (Harbor Front). Two-way ticket per head at SGD$47; inclusive of all fuel charges, misc charges, insurance, etc.
Exchange rate at that point in time; SGD$1: Rp$7, 400. So just change a small sum & you'd be titled a "millionaire"!
However, stuffs (watches, clothing, wallets, belts, etc) sold there doesn't come cheap & at high chance, are imitations. Folks there knowing that we're foreigners, will raise their selling price to gain a better profit margin; taking us as Cai4 Tao2! Apparently, bringing an auntie with persuasive bargaining skills gonna do you good.
Everyone knows about KFC. & now we even have BFC!
