Theater to flee, not serious. This day, 14/11/19, we had two seats for the show "Dom Juan" at 19:00. Upon our arrival it is displayed on the door: "opening the box at 19:15". At 19h15 when removing our seats we are told that this room only starts at 21:30. We had 1:15 of transport to come to this theater and go the other way for another 1:15 of transport.
