One year in the 1990s, on the last working day before the Lunar New Year, all the companies in a small office block had closed for the holiday, so the management staff turned off the electricity at the mains, locked up, and left.
They didn't know that a lift mechanic was still in the building, in the lift. He spent the entire holiday trapped in the pitch dark, and presumably quite small, lift. Whether the total holiday that year was three days or longer, I don't remember.
I think of him every year at this time.
