When I was an apprentice I worked with some old bell guys that had taken early retirement from the phone company. A couple of them thought the best way to run cable was to just pull it out of the box and use it without marking. Then they would terminate the cables and tone out each location. So cable one might be on the first block and cable two could be on the fifth block. This seemed very logical to them.
Oh, by the way, one of these guys told me he would carry a big bag of scrap wire on his truck. At the end of a shift he would call the foreman and tell him that he had to work overtime to get the job done. He would dump the bag of scrap on the floor at the MDF so that it looked like he had been working like mad just in case the foreman came by the jobsite.
