I would expect alcohol to be banned in Quatar, because it is a muslim country. But did the games ban non-alcoholic beer as well?
In some markets, non-alcoholic beer is the only beer that you are allowed to advertise anyway (even though companies use the same brands for alcoholic beer as well ... which gets around that rule in practice).
BTW. in the '80s, some enterprising nut-head tried to sell beer to Saudi Arabia: It was sold in freeze-dried form, and did of course not contain any alcohol. My dad tasted it and said it was awful.
