Mmmmm ....
Well I first started working in Dubai back in 1980 ... it was a wonderful place then ... I have many fond memories of the place ... I recently finished a 4 yr stint there, with a fantastic 10 yr stint before that down at ADA [Abu Dhabi] ...and I have to say I have enjoyed it greatly ... but attitudes there have changed over time as has the money you can make and the costs of living only goes up.
In my opinion those glory days are over ... it is now very much a 'HONG KONG' in the sand ... and yes my views may be biased because of my memories of what it was.
For a 'new chum' going therefor the first time it might be new and exciting, keep in mind you will very much be a 'resource' to be used and exploited .. keep an open mind, keep smiling and don't think your going to change anything .. good luck.
Alas my 'glory days' are also over as my age now prohibits my holding a license there ... but DAMN it was good whilst it lasted !!!
