"The cables themselves in the office were not terminated into floor panel sockets, they were just deployed as flying cables to be plugged straight into a device and the only identifying marks on the cables were written on the cable using a biro,"
To balance that story out a little, our company has done a job very like you describe. You, as IT probably wanted a proper job with wall and floor plates etc. But the customer PHB signing off may well have been one of those who thinks that wall/floor plates are an expensive luxury and insists on corner cutting. In our defence, we did label everything properly but if I'd had my way we'd have walked away from the job.
