Very brave of her to venture into those Muslim countries alone as a woman. I guess they're a bit more open towards Western tourists these days, but still. I've been to Jordan about two years ago on a work trip, and although the people are very friendly, you always have this feeling that you don't want to mess with their security or police. Obviously no alcohol served at any restaurants, women were covered up in burqa's or at least hijab's.
I recall how our taxi was inspected each time for explosives when we arrived at the hotel. Also our driver had to obtain a police permit in order to transport us as foreigners, etc. At the airport they were extremely strict, inspecting at length the magnets on the fridge magnets I bought, taking away aftershave, etc. You almost feel like a criminal!
