I suspect the Qataris are wondering what all the fuss is about. With Bud zero on sale in the stadia, watery piss is already available.
Had a similar experience at a rugby World Cup match in 2007. England played the USA in Lille at the yob-ball ground, which has a no alcohol policy. It was all readily resolved by staying in the bar on the Eurostar, heading to the cafes for a few extra scoops before KO and taking the trusty hip flask into the ground to give the non-beer beer a bit of a boost.
