I'm always struck by the presumptuousness of such places as this in the expectation that you will be able to intuit all of their rules and regulations and protocols and policies and directions without sufficient signage or human help whatsoever. everything is aimed at making things as simplistic and easy for their own employees while downloading most of the onus for their protocol overload on everyone else.
I picked up two coils at the facilities down the road from each other and who knew each coil needed its own CTPAT inspection?? I was kicked out of a huge line up just so another employee could walk around my truck with a mirror on Wheels and do what another employee had just done.
This is a perfect example of the wastage and lack of Common Sense just to service protocols and drive up the costs, that pushes organized labour jobs offshore.
Protocols and policies should be there to service people. Not the other way around.
