I recently attended the Build Expo at the Walter E. Washington DC Convention Center on August 18 & 19 2010 as a vendor. I was notified after signing up for a trade show at a cost of $1850.00 for a 10 by 10 spot for two days. That we would not be able to unload our displays, that it was a Union Dock and the Decorator would be charging Drayage. Beyond the charges being excessive $166.00 per hundred pounds and a 200 lb. minimum. The kicker was them placing everyones load onto a very heavy oak pallet and weighing it with the fork lift without zeroing out the weight of the pallet before weighing the load. Adding 80 lb. to each vendors display. The pallets were returned with the same fork lift to do it again to the next vendor. I personally find this to be criminal, reminds me of a mafia style shake down. If we complained, we would not have been allowed to display and lose the original cost of the show spot, some folks had 6 spots representing over 11 thousand dollars. The dock Extracted well over 100, 000.00 dollars from just this one show.
