Good on BA. Like PC767 says, Euro royalty in general tends to be painfully aware of their status and their impact on the lives of their subjects and other pax. Yes, you get the occasional stroppy prince(ss), but the older ones tend to be unassuming, considerate and try to get there with a minimum of fuss and pomp.
As for Africa, yes, unfortunately in Africa and the Middle East the whole "the more important I think I am the longer I'll let you wait" adage is well alive and kicking, especially by despots, dictators and general wannabes.
