This may be typical for Argentina but it was actually copied from the Greek unions and anybody else protesting doing the same thing. As a matter of fact, I remember the taxi strike of 5 years ago when access to all airports in the country were blocked, and even a case some 20 years ago when the fans of one of the local football clubs did exactly the same in Heraklion where I live because a number of their players had been punished for a reason I don't remember. Please give credit to Greek inventions! (Mod, I'm Greek!)
