Yes, Cairo is dangerous!

At the hand lugagge control, after passing my bag in the x-ray.
The officer at the machine say something in Arab to the a man dressed as a military just behind me,
the same man take me and my bag to a corner, he open up the bag start point to my
computer and show a negative sign with hes head,
I without understand keep looking what he wants to say, after that he found a bottle of
zivania (Cyprus home spirit) that i just got on the last fly from larnaca
and he tell me that i couldn't take it to the air plane.
I said the bottle was still close from the duty free shop bag.
Finally without understanding each other the officer show me a sign that if  I want to take the plane
I must give him cash, I disagree and he start to look around if somebody was looking at him, and after 3 minutes he realised i wouldn't pay for it and he let me go,  later on I could see how he tried extort 2 more people. Cairo, Pyramids, Shisha??? no thank you.
