How do blind people know when they're done wiping their ass?
In their efforts to be more energy "sustainable" all light switches at the Joint Forces HQ are on automatic timers.
If you aren't completely done in 5 minutes you're getting the Stevie Wonder treatment.

Since I am a humane and not an OWL, my line of sight does not swing that way. Most of us have to guess we done it right.
What is going on here, some people are in and out in a few minutes, some take the news paper and read it while waiting for the body to do it's job, may take 30 minutes or more.
If there is live fire above their heads the problem should only take 15 seconds or less. I do not think wiping would even come into this in that situation.
So frigging adjust guys and gals. Carry a pen light in your pocket, lights go out while you are reliving you self, you can find the paper and the door that says exit.
Next thing to come up may be the laundry personal that complain that they have to handle and wash the uniforms covered with blood from combat or body fluids lost to fear in an attack.
