Fun fact a mate back when I was an Apprentice told me of his day (he was an apprentice air conditioner) He was on the top floor of (the AMP building?) in Perth and noticed that the lift guys had finished.
He stepped inside and it dropped about fourteen floors then started ascending. Stooped and then dropped again and again with him screaming the whole time.
Yep, the sign DANGER LIFT TESTING IN PROGRESS had fallen over and they were testing the brakes and the lift cables in a safety inspection. *DO NOT WORRY, THIS CANNOT HAPPEN, ONCE ALL FAILSAFES ARE INSTALLED*
When the lift eventually stopped instead of sympathy, the told how the works supervisor abused him for being in the lift and yes young Adrian laid him out and was sacked.
However, he received a MASSIVE compensation payout due to their negligence, which has no doubt changed his life.
God works in mysterious ways! And know Adrian won't go in lifts anymore. true story.
That incident was EXTREMELY rare. Knowing this I have no issues in lifts at all, I just felt to share the story as a fun fact.
