Some people in Spain take their olives very seriously indeed. Like this chap from Gijón who received a dish of olives as a tapa to accompany the drink he'd ordered.
Upon trying the olives, he apparently 'went mental', complained about the olives, insulted the bar owner and proceeded to cause €500 worth of damage to the joint, throwing tables and chairs at passing vehicles, and smashing glasses and bottles.
Perfectly reasonable behaviour, you might well think. And I'd agree. What sort of disgraceful behaviour would make you totally flip out?
