Bribery costs individuals, businesses and economies billions of dollars each year, and there are many international laws and conventions against it. But what happens when your firm operates in a part of the world where it's still the norm? In this episode we speak to three business people with first-hand experience of backhanders and ask how they can be avoided. One of them tells us he pays bribes as a matter of course, but if you're not willing to, does that mean you simply can't do business?
