The sell of liquor is permitted to Qatar airways only, which also operates QDC. As many of you are aware , it's only a matter of time till QDC is shutdown and sell of alcohol will be limited to 5 star hotels. Most of the local public is pushing for that & it's in the advisory council agenda for some time now as it violates Qatar constitution.
Permit for selling pork can never be passed by authorities without the approval/recommendation of both ministries & advisory council. And this will not happen anytime soon ;)
