Another possibility —
I work with movers a lot. They will hold or keep pressing the “door open” button to get as much furniture and boxes loaded into the elevator as they can fit.
On some older elevators, if you hold or keep pressing the button too long, a little alarm will sound and the doors will close and sometimes will NOT bounce back, even if you wave your arm in from of them, like they usually will do. If you’re in the way, it’s very scary!
There is a red “hold” button in newer elevators, which works better, you still get the alarm but the doors don’t close.
I avoid elevators.
Last summer was hell because of Himself being in hospitals.
