My Zero-Indexed Elevator In Portugal

Finally, an elevator designed by a programmer! The ground floor is 0, not 1, because arrays start at 0 and so should our buildings. That green button is practically screaming "I'm the selected index!" The non-programmers must be so confused when they hit "1" expecting the lobby but end up on what normal humans call the "second floor." Bet the building's GitHub repo has 47 open issues about "intuitive floor numbering" that the dev team has marked as "won't fix" and "working as intended."
