It was'nt so much at the dark TM, but at the hubs where the drivers would work the dock go out and hook then come back in clock out to be off the dock clock out again to be disp. back to their TM.
I guess that could screw things up if people operated that way. The thing is, if central dispatch knows you're at a dark terminal there should be something in the computer system to pay the driver for those drop & hooks. It's a shame, it could have maybe been a decent place to work.
