Use the taxibooth IN the terminal. Look for the fixed rate. Do Not use taxis outside the terminal (the yellow and black ones) even if they have their booth..
Most rude staff I have yet to encounter. Mass chaos, attitude and policies that don't make sense. No water can be brought on board either. Best thing about this airport, leaving.
Nothing to do. People really rude and are always trying to take advantage of you. be aware that taxi drivers are the worst thieves in town. Always use o smartphone gps or a map and check the fares.
