It is common to hear phrases such as "Mr 10 percent" as a reference to powerful leaders in various countries. For instance, Pakistan President Asif Ali Zardari is called "Mr 10 percent". 10 percent cut from every contract. This is not unique to Pakistan. In India, many regional party leaders (basically, they and their family own the political party) want 20 percent cut.
When one hears 2-6%, it is just the floor.
