This was a horror story past down by my fellow workers at a high school theater. "Pain" Webber, the Auditorium manager before I got there was I guess... a pain. The Loft blocks were a little too noisy so he decided that the only way to fix them was to oil them. So, "Pain" took a bucket of grease to the grid and started to grease all the blocks. That that didn't last too long because the grease ran down the load lines and all over the goods. Which ruined them. What led to his early dismissal was that he bought all new drapes for the theater without approving it with the admin. Thats the story. PS. what really sucked was that the load lines still had grease all over them, so whenever you had to deal with them you had grease and dust all over your hands.
