     Dominique, gilet jaune de la première à Saint-Denis (Seine-Saint-Denis), ne manque jamais les manifestations de soignants organisées dans sa ville, chaque mardi devant l’hôpital Delafontaine et chaque jeudi, devant l’hôpital Casanova, car pour lui, "blouses blanches, gilets jaunes, c’est le même combat !"
