While walking around downtown Calgary yesterday, I encountered an outdoor set of escalators (which is sort of weird given the climate), but it was the sign on the escalators that really caught my attention:

I didn’t know which one was the down escalator and which was the up one, so I kept right on walking. I mean, what if while going up the down escalator I ran onto someone. That would really be awkward…

Oh, and just to clarify, the acting like stairs bit referred to the escalators not working.
