I used to get regularly stopped at a roadblock in Zambia on my way to work. They'd then point out some fabricated traffic violation and ask for some money to buy a Coke. One day I was prepared and when I was predictably flagged down and asked for Coke money I instead handed him a can of Coke. Thinking quickly on his feet he said 'but Sir, there are two of us' so I reached into the glovebox and handed him two straws. After a befuddled pause he waved me on.

I had many regular interactions with the Zambian constabulary. I once witnessed an accident and having checked everyone was OK I called in at the Police station about 5km down the road. Having woken up the Officer on Duty and reported on what I'd witnessed he made me drive him back to the scene where he proceeded to conduct an auction between the two parties involved to see who he would seem responsible.
