Maybe I should just stop wondering about doors and spend more time contemplating world peace, but sometimes I can’t help myself. I’m staying in what looks like a fairly new hotel. After driving into the secure parking garage, I entered through this pair of doors into an elevator lobby (these are the only doors in the elevator lobby):
The doors don’t have any type of lock on them – there is typically someone at the vehicular entrance to the garage and the elevators require the room key to access any floor except the main lobby and parking levels.
Here is the elevator lobby for reference:
The next morning I attempted to leave the elevator lobby through the same doors, but could not open the door on the right.
Of course I stopped to check it out, and clearly the surface bolt was added to the LHR leaf. But why? Any theories? (I’ve got one.)
