More than six million litres of beer will be downed by visitors to this year's Oktoberfest in Munich. They will also eat half a million chickens and almost 100 whole cows during the 16-day drinkathon. The weak German economy has meant beer prices have barely risen since last year. Visitors are expected to spend nearly Eu1bn on hotel accommodation, taxi fares and beer drinking. And city coffers will be swelled by fining weak-bladdered revellers Eu35 fine for urinating in public.
