Wiesenhof Lanseria Airport

They have absolutely no customer service. Been there 3 times in 3 weeks cannot get one non-alchoholic beer. Its an airport, airlines encourage travelers not to consume before or during flights. What does Wiesenhof do, sell it by the tanker full. Writing or complaining has no effect. I would advise anyone to avoid this place like the plague. not interested in customers at all.
