Woman is knocked flying when supermarket worker pushes carts down escalator

This is the moment a woman is knocked flying into the air after a hapless supermarket worker pushes shopping carts down an escalator. The shopper falls on the floor after being hit by two trolleys as seven hurtle past her and smash the supermarket's glass windows. CCTV footage shows the worker at the Almaz shopping centre in Chelyabinsk, a city in west-central Russia, dumping the carts down the escalator without a trolly strap.
