Not an employee but a participant
My group went to a pirate ship themed escape room. One of the puzzles involved pressing lit up labeled buttons on a wall in a particular sequence to unlock a door. A common theme (to me) in this room was water. There were exposed water pipes that had cartoonish signs on them reading "do not touch", and one of the lights on the wall read "water" and the light behind it was out. I had to have fixated on this for a good 30 minutes; I tried unscrewing parts of the water pipes, pressing the water button while trying to open parts of the pipe, everything. After we finally moved on and finished the GM told us that the room had nothing to do with water, I was actually just messing with their water system.
