When I was Kmart, we had an employee locked in the store the WHOLE NIGHT.
He was out in the garden shop, putting away last minutes layaway into storage (it was the holiday season, and the indoor part of the garden center is converted into a makeshift layayway storage area until Spring). Everyone else in the main part of the store zoning.
The manager had to leave in a hurry... His mom was in a nursing home and he was called by nurse for something.
So he got on the PA and paged everyone to service desk. Everyone came up... Except for Bob, who was still in the garden shop. Bob was an older gentleman who was hard of hearing....
So we left. The manager assumed the service desk person let Bob out and the service desk person thought the manager let him out.
Anywho, Bob realized he was left behind when the lights out. Now, Bob didn't have a cell phone and the phone in the garden shop needed a PIN code to dial an external call. And Bob knew that the alarm would go off if he tried to go back into the main part of the store... So he spent the night in the garden shop.
He wasn't outside, but the indoor part of the garden shop isn't heated.... So I'm sure he was quite cold. What a surprise for the 4AM opener.
From them on, the manager had to a double check of the store and if Bob was working, giving him a time to be back up at the service desk.
