A recent United Nations report has Afghanistan as one of the most corrupt countries in the world.
The UN Office on Drugs and Crime has just published a report that says half of all Afghans have had to pay a bribe for a public service.
The report said Afghans paid over $2.5bn worth in bribes over the last year alone, exactly the same figure generated by the country's opium trade.
Al Jazeera's David Chater went into an Kabul pensions department office to get a sense of the country's widespread corruption.
