According to one of the most respected journals in France - Le Figaro:
Quote
"The public, 5,500 people on a gauge of 11,000 (it was necessary to hide the unsold seats by wide black curtains) does not suspect anything. But between the entourage of Nicki Minaj and the Arkéa Arena officials, nothing is going right. Despicable and unpleasant, the Americans refuse to open the door of the backstage room where the star is, and no longer speak to the French."
"the design of lights on certain pieces requires a hundred times more electricity than the European laws allow: 3 amps instead of 30 milliamps. The American entourage has understood and instead of solving the problem, trying to get through each room. In Bordeaux, the problem was reported late Saturday morning by French technicians Arkea Arena. As soon as informed, Jérôme Langlet, the director of Lagardère Entertainment, who is responsible for operating the room, asked the Americans to comply with French legislation. One solution was to remove the special effects that were causing problems on some songs. Refusal of Americans. Jérôme Langlet, who knew the horror of the Bataclan which Lagardère was co-owner at the time of the attacks, does not yield: "There was a chance in a thousand for there to be a short circuit and in this case, people die . I absolutely refuse to take this type of risk. We must respect our laws. "
