I never got an invite to a private compound or where the locals lived.. Dry is relative.. But I hear Johnnie Walker and more can be found.
This is just picking on the workers.
I’ve heard that there is an underground market where you can get alcohol and pork.
We used to send over programmers to work with the BBoME. Sometimes they simply couldn't get their passports back after several months of work, even though the contract clearly stated no more than 3 months in country.
Sometimes it took a call directly to one of the managing partners of parent HSBC to have the passports waiting at the airport in short order.
What goes on behind the walls of the British compound certainly stays there.
