A typical Saturday at Mercado de las Ventas - one of Madrid's largest markets. But many stall owners and shoppers here - already hit by tough austerity measures - will be feeling the pinch after a VAT tax hike came into force today across Spain. VAT on meat and fish increased from 8 to 10 percent though essentials like bread and milk stayed the same. Many of these stall owners have opted to take the hit for now, but customers are still upset.
