Less aggravated now.  Finally got out of there.  Receiver took 6.5 hrs to get my trailer unloaded.  Typical unload time is up to 2 hours.  And I am only allowed to work so many hours.  But ... that is in the past.  Now I can relax a little.  (They still left me a mess by damaging some product and refusing to take it.  But I will deal with that tomorrow.  Hopefully work will tell me to toss it ... or let me take it to a shelter.  It's food.  Just the outside box in which the actual product was in was damaged.)
