Hi Holger I just got back from the BYH-festival in Balingen. The beer sale was the best and most effective I have EVER seen. I did not spend more than max. two minutes to buy a beer through the entire festival !!! The organizers had put up about 20 stands around the festival-area where you bought beer-coupons. Then when you bought your beer at the beerstands, there was NO exchange time at all !!! You just exchanged three coupons for a beer and the beers.....the beers was just flying over the desks at UNBELIEVABLE speed Are you planning a similar idea? 'cause the beer-sale in Wacken has always (as one of the very few things) sucked big time.....I mean if you only wait about 10 minutes to get a beer at the WOA, then you are a very lucky fella'
