I know a chap that has been driving in Manila for many years he doesn't even have a licence in his home country, just bribes the police any time he gets stopped.
He has a business there and is not short of cash!
Only had to do it once 500 peso bribe when I hesitated at a junction because the road I was about to turn into turned out to be one way, we got away with it because we were taking the kids to hospital at the time, I let Ana deal with the police and the bribe she is good at that
