Quaid and the thousand dollar staircase. [1] - Extension

Just extending the original post... What Quaid had decided to do, on this ever so busy shift, was to connect a hose to a tap in the back area. He then decided to hose down the entire back area, and then mop it all up, (1/2 an hour) then he realised that the stairs also required a good clean so he decided to hose them down too, only to realise there was a: no drain at the bottom of the stairs, and b: that he had to mop it all up. On completion of this ever so useless task, (only one of many), I went to check out this job of his. What he has managed to do was dislodge all the dirt and sediment that had clogged up the non-slip tracks at the edge of every stair, and since there was so much, (30 years worth, lol), he had actually given up and left the stairs in a worse state than when he begun. I was ready to walk out then and there...
