A woman from China stands with a shopping trolley in front of a Duty Free store at the Fraport airport in Frankfurt November 14, 2012. Frankfurt airport's new Mandarin-speaking personal shopper service is just one example of how leisure and travel firms in crisis-struck Europe are trying to tap into the seemingly inexhaustible spending power of Chinese tourists. Value-added tax (VAT) refund data shows that Chinese travellers, who could overtake Germans as the world's biggest spenders on foreign travel this year, top the tax free shopping leaderboard in European cities like Paris, London and Frankfurt.
