The escalator support collapsed before I reached the lower floor and I fell into a deep dark smokey pit where I could detect the odor of fire and brimstone.
Not exactly something bad. However, the escalator I was riding suddenly stopped running. I and about a dozen riders then walked up the escalator stairs.
Walking down stairs isn't too bad for me, depending on the height of each step. Elevator steps are almost twice the height of most steps, which makes walking up and down the elevator steps to be difficult for me.
