God, I hate shows, I have worked a bunch. The worst were when I worked for a concrete block manufacturer. We would bring in 6-10 pallets(that is 18,000-30,000 pounds) of material to build the booth. 10x20 of concrete pavers with walls and planters built over that, with a grand or so worth of plants. I designed them and built them and usually won best of show. My unofficial job the whole show would be to give the damn thing away so we didn't have to haul it out. I could usually do it too, Thank Cod.
The worst one was also the first one that I worked. Brand new on the job, about a week. My company didn't have a booth, one of our vendors did. My boss, however, was friends with the salesman that was supposed to work the booth, so he made ME work it all weekend while he and his Buddy went out and partied. Talk about clueless-I didn't know the product or even what I was supposed to do, really, so I got drunk myself and stood there passing out this guys cards, writing his home phone number on the back, the salamander.
