Fun fact: The reason old firehouses have poles is because back when firetrucks were pulled by horses, the horses would sometimes get loose and try to walk upstairs. The regular stairs had to be swapped for spiral staircases (too tight for a horse to climb) and poles were placed to give the firefighters a speedy way to get downstairs.
Now imagine in the modern day the Ghostbusters have to put up with ghost horses coming upstairs now that they can simply float through the floor lol.
