Worrals,
Not only do the bogans not leave the Bogan Terminal at DOH, they can't get a drink there, either. And if they do escape & make into town, they'll find that booze is not as readily available in Qatar as it is in Dubai.
They have easily-seen yellow bag tags, get off and on the a/c through the rear doors, are processed through and stored in a separate building from, and are generally kept well away from, the premium punters (and the locals).
