A couple days ago when I was waiting for the train to go home, I saw a man walking at the bottom of the escalator (the wrong way). For the 5 minutes I was standing there, he was walking slowly nearly leaving the escalator as it spooled around and carried him back up continuously.
Perhaps coincidentally, the next day, that escalator was blocked off. Hmmmmmmm.
That reminds me of the time I got in trouble at ZCMI mall(back when it was still ZCMI). I was on a field trip with the orchestra (led by Mrs. Tuke. Or Tooke. I really have no idea how it is spelled) and I ran up the escalator the wrong way along with an accomplice. There were a couple mall policeman at the top, and they told us not to do that again. It was a mild brush with the police, and I didn't mean to frighten you with the title of this post, but one has to get attention somehow.
