OK, I'm talking back in the 80s.
Had a hotel, kept getting shut downs apx. midnight, owner didn't want us out til morning (no non emergency o'time). Every morning elevator would be back running. This went on for 3 months, intermittently. Stayed with elevator on own time, nothing happen, finally stayed out of sight fooling elevator (it didn't know I was there). Then it happened, a local college kid would stop 1 elevator of a duplex (that's why it was intermittently reported), sneak a roll-a-way bed on top and sleep. Cleaned everything up in morning and left. Every night except when he saw me there.
