Before you take a stand on this issue,havd you ever returned to Nigeria throuh that airport?if you havent,there is no way you can understand the behaviour of these so called security operatives.
Every scrutiny in that airport[most times unneccessary] is only done because gratification is needed....you must settle at every checkpoint at the airport.One can not be in the mood to part with money evertime especially when its extortion in any disguise.
I am opportuned to havd travelled through some other aiports in europe and america and i had never been called by all types of uniforms at point of exit; if any,its only customs and that is when there is scientific proof that i did not make declarations.But in Nigeria you have NDLEA,CUSTOMS,NAFDAC,AVESEC,POLICE,AIRFORCE and so many i cant remember infact its only lastma that is not there.
