If you work at a hospital, LE, in manufacturing...
I can see a need, but these days humans and utlities cost too much, and crime is a huge issue.
Many years (decades!) ago I worked for one of those inventory firms that go into retail stores and count the inventory.
The inventory did not start until the store closed, which often meant that the shift began at 9 or 10 at night.
That meant we went home at 2 or 3 or 4 in the morning—and really appreciated any fast food places and/or Walmarts in the area that were open.
