A US woman was arrested for calling 911 after a restaurant served her cold onion rings. Sharita Williams, 30, of Houma, Louisiana, told police the food was cold when she received it and the waiter refused to replace it. So she dialled 911 from the Malt-N-Burger restaurant in Thibodaux, reports the Daily Comet. Police turned up - but only to arrest Williams for wasting police time. She is due in court in December.
