Having stood watch in the dark and the cold and travelled through convoys surrounded by foreign nationals, any of whom may want to attack us, I can attest to the difficulty of judgment calls.
Scan the sidewalk menus for some chilli crab or the local staple ayam buah keluak (chicken cooked with a dark, oily local nut), or just sip a glass of wine and watch chugging "bumboats" ripple the reflections on the river.
