"Don't They Know It's Friday" by Jeremy Williams serves as perhaps the only cross-cultural guide book of its kind to a visitor to the Gulf. Several Gulf countries are "emerging" countries and as such it is easy for the Westerner to expect similar levels of social systems and standards as it exists back in their country. Reality however is different.
The book provides numerous commentaries on the Middle East geography, working styles, food, clothing, body language, money/banking, law and more. It has a suitably presented background on the all-encompassing Islamic influence in the Gulf 'way of life'. I particularly enjoyed the author's treatment of how one should diligently tailor their attitudes in the Gulf and how uncompromising, impatient attitudes can lead to frustration and even business failure.
While the book can be seen as patronizing to the first time Gulf visitor, I think it does well in presenting a cautionary education to general readers without assuming the knowledge and experience of anyone in particular. The author's 35+ year career as a diplomatic officer saw him stationed at several Gulf countries. Without arrogance, however, he has managed to compile the guide after consulting others, including Gulf scholars of law and Islam. In that regard, this isn't really the opinionated views of one man.
