Paris Hilton has been denied a discount at her own chain of hotels. During a live interview on a Scottish radio station, the heiress tried to reserve a room in her own name at the Glasgow Hilton but the booking clerk refused to give her the corporate rate. He told the 'House of Wax' star: "There is no discount I can initiate, I'm afraid". Instead, he offered the hotel heiress a standard queen-sized room the full rate of $310 per night. Meanwhile, Paris recently ordered her helicopter pilot to make an emergency landing on a German farm - so she could use the toilet. The actress-turned-singer was touring the European country, before the start of the football World Cup, when she reportedly made the surprise request. Paris even got her security to stop the family from entering their own bathroom so she could relieve herself in peace. A source said: "She gave the farmer a bit of a shock. Her bouncers even blocked the farm door so the family couldn't go inside their own house while she was using the loo."
