Bribes are part of the cost of doing business absolutely everywhere.
Same right here in the US, just there is a more clever system of laundering the bribe before delivery to the taker.
I was a naive Southern boy when I got my first "real" job and was flown to Chicago to help man a booth at McCormick Place (back when the Consumer Electronic Show had a summer show there)
Well I may have been naive but the owners were old hands.
I was amazed that we were the first booth that got to tear down and get the trucks loaded to get out of town while others waited hours (and a few, days) until I found out we had bribed the correct Union workers.
Just another reason to hate Unions.
