For the police incident, a taxi I was riding in got pulled over because I (as the front passenger) wasn't wearing my seatbelt. So from the start it was quite obvious what the officer wanted. He got the drivers' license, held it up to the sun to see if it was genuine, was checking the quality of the car tires, if the license plate was properly attached at the front and back. Made a big show of it. Then he asked the taxi driver to come around the corner and talk. When the taxi driver got back, we asked "how much" and repaid him the bribe he had to give. $5. The good news about rampant corruption is police can be bribed cheaply.

For the customs officer, I was bringing a box of stuff into the country as gifts to family. He was reluctant to let me through. A lot of ums, hmms, and lengthy "thoughts". I knew his thinking would be quickened by a US $20, but eff that. I wasn't doing anything wrong, so no bribe for him. I eventually made it through.
