Dreadful beyond all telling. If you can change do so now. If you must and you fancy a drink take your own as the Captain may not allow served on religious grounds. If you like Coke, they may tell you that they haven't got any, check the drink cart, they do for some reason they all want to take it home. Safety is a joke, and service is non-existant. they all seem to come from the upper echelons of Egyptian society and think that such matters are beneath them.
This is in total contrast to being in Egypt where I was treated with nothing but charm and courtesy.
