Bill, I used to go through the same BS when I worked for The Fisherman Magazines and we had a booth at the New York National Boat Show. We could back up to the loading dock, but THEY had to unload the gear on to the loading dock, then take it to the location inside the hall where it was to be set up. They guys at the loading dock pretty much told us that if we wanted to see that stuff, at least in one piece again, it would require a $50 tip. After we set up the booth, which took all of 20 minutes, we were not allowed to plug into the power strip behind the booth. That required a union electrician - and guess what, it was a $150 fee for plugging in a single plug. Ya gotta love NY and NJ.
