Egypt is a paradox. In the words of a colleague, it is "hypothetically Islamic," meaning that it is important to appear Islamic, and go through the motions of being Islamic, but that is because everyone else is Islamic, and you do not want to lose face. In other words, one does not do something because it is Haram (which means absolutely forbidden by the Koran), but because one does not want to be seen doing it. Behind closed doors, it is fine for all Egyptians to drink and have sex with unmarried people, but this is not talked about.
On to more superficially obvious things...
-In the sha'(g)bee (popular/middle class/egyptian) parts of town, everything you could ever want is in a specific shop on the street. If you live above one of these shops or markets, a the best way of getting things you want is by letting down a bucket attached to a string, with some money in it and a list, and then pulling it right back up.
-For the upper class, there are malls. I went to one mall, called city stars, seven stories, more western and opulent than the west actually is, had absolutely everything that you could imagine, I wish I had taken my camera.
-There are a few traffic lights, but they are meaningless and should be disregarded. Intersections can have four scenarios.
1) they are directed by a traffic cop
2) there is no traffic cop and it is honking-match grid-lock
3) the big vehicles and the cars moving in the flow win and you wait your turn
4) you honk your horn and go (most common in the back streets)
-There is an abundance of police officers doing nothing.
-Smoking Hashish is more morally and socially acceptable than drinking beer. This is because the Prophet Mohammed explicitly condemned beer more times in the Koran than he did hash.
-It’s not gay to walk elbow to elbow. Lots of men do this, it’s how Cairene men walk.
-It’s been cool to litter for 5000 years. Poor people will go through the trash on the street. There are some trash disposals, but waste just sits on the street everywhere.
-When there isn’t a price on something that means that you are supposed to bargain for it. In certain scenarios an accepted Egyptian/Non-Egyptian price for things. This can also be true in certain restaurants where the non-Egyptian menu prices are standard, and you have to fight to pay what the guy next to you is paying.
-There is a beer delivery service. This is because there is no way to buy beer otherwise during Ramadan. After Ramadan these places open up, as do the bars.
-Egyptian kids love saying “What’s your name?” “Welcome to Egypt” and “How are you” to you if you are white.
-The society is class based and will stay that way. In different parts of the city, there can many self-contained areas of the wealthy or the poor.
-Lots of men have a “raison” on their head, or a mark. This means that they pray a lot.
-Most women are veiled. This means that you do not touch.
-There is no drainage system for water because it never rains. Even so, when there is water on the street it just festers for days.
