Black Shower Again

So I was in a hurry this morning to get out the door. I scurried into the bathroom, bleary-eyed and semi-conscious. I turned the water on, and GUSH! It was all black water again!! It was just a short spurt, but I could see the little floaties of black in the black water.... and to think that last time it did that I was IN the shower UNDER the water!?!!! Gross!!! I think it's time to have a little chat with management.
