One time going into my 2nd or so 101 class, I was really out of it. When the doors opened on the 3rd floor, I got out and found myself in an incredibly white and brightly-lit room surrounded by those fencers- which, when it happens to you, is pretty fucking terrifying. They look like beekeepers with swords. I desperately stumbled backwards towards the elevator but the doors were almost closed so I was TRAPPED. Someone there asked me if I was ok and I said, "I'M IN THE WRONG BUILDING." (Note: I saw the doorman as I was walking in but in my surrounded-by-fencers state somehow rationalized it with the possibility that he works for 2 buildings that have a door between them so he has easy access.)
The thought that I got off at the wrong floor didn't occur to me so I waited for the down elevator and walked out of the building until someone from my class recognized me and asked what I was doing.
So that's my experience with the manhattan fencing club.
