Since the building was originally planned to have only 20 stories and was enlarged after this fact, the builders forgot to adapt the elevator shaft to accommodate the extra height meaning that there is no elevator from floor 21 to 47. Even more shockingly, the oversight was not spotted until the building was almost completed.
Translated from the Spanish...
Pedro: Well, the building almost done...
Hector: Yes, and all we need to do is.... wait a second....(very long pause as he examines the blueprints, furiously flipping the pages back and forth)...I don't think....uhhhh....where are the elevators for floors 21 - 47???
Markus: WHAT???? Let me see..... OH SHIT!!!!
Pedro: OH SHIT!!!
Hector: FUCK!!!
Redondo: Oh my God!!!
Maria: You fucking idiots!!!
