I worked at the BJC for a summer. Concessions. It was ok. really depended on the show. Clapton, for instance, was really mellow. The people were generally well-behaved. or drunk. The Gaither Vocal Band, on the other hand, had some of the nastiest people I've ever encountered. Our soda machine ran out of flavor syrup for Diet Pepsi during the midshow break and i had people screaming and swearing at me like you wouldn't believe. I guess going to a religious gospel show'll get you riled up.
