On the phone from one of his regular haunts, Dubai or Johannesburg, "Monsieur Coco" was getting into his stride. "I'm going to have you whipped, you fool," he shouted, in a volley of insults and threats aimed at the boss of a mining subcontractor, who was taken aback by the violent outburst. "If you don't stop, you're going to have to leave the city, you're going to have to leave Katanga". Coco Muya doesn't take kindly to being told "no" in business and has his own distinct way of making that known.
