Everyone is in on it
While walking around Cario, a elderly man befriended us and, after a short discussion, invited us to dine with him at a local joint...which ended up being a plastic table put under a tree on a curb. He paid for the meal but then said "you can give me a donation for our church...say 50 Egyptian Pounds (which is around $10). Little did we know the rest of the evening we would be taken around Cairo by this guy and eventually find out he, along with every other person in Egypt, is out to rip off "whites".
