Oops, did my job a little too well apparently; dispatch was planning a double run for the freight I was to load, and I managed to load 95% of it into one trailer anyway. No point in doing a second run for freight that would barely fill a quarter of a trailer! (had I known that was the plan I would have probably saved half the freight I did load for a second trailer. But all I was told was load what I want so long as two specific shipments made it in at the end!)
