In Poland's late summer heat, dozens of cars and trucks line up at the Lubelski Wegiel Bogdanka coal mine, as householders fearful of winter shortages wait for days and nights to stock up on heating fuel in queues reminiscent of communist times.
Artur, 57, a pensioner, drove up from Swidnik, some 30 km (18 miles) from the mine in eastern Poland on Tuesday, hoping to buy several tonnes of coal for himself and his family.
