I will email you bose-x, thank you.
Apologies for being one of those suggesting Egyptians are a bit "sharp". I've been to Egypt (not in a light aircraft though) and while I think Egyptians tend to be very straight, proud, and honest to their own countrymen, there is a tendency among many to regard tourists as absolutely fair game for any con trick and if you are gullible you will get dozens every day just by walking down the street. This is common to much of the 3rd world and one has to watch it. It's bad enough in some places in Greece where you have to pay cash in hand for avgas - at an international airport and this is an employee of Olympic Handling.
I'd expect international airports are generally OK because they have to be secure, but it's next to impossible to find out whether they have avgas for example. I always fax, but often the reply bears no relation to reality. And a thick wad of US $ is the best thing of all.
