Pizza Hut, the world's largest pizza chain, is downsizing in yet another country. Following the cessation of its operations in Turkey months ago, troubling news has emerged from the chain's UK restaurants. The popular pizza chain, with a history spanning 67 years, is set to close 68 of its outlets across the UK, leaving 1210 employees jobless. In addition, Pizza Hut had entered into bankruptcy management in the UK last year.
