"In year two, our laser-tag business was struggling. Attending the amusement industry's trade show was our only hope. It was booked, but we got space outside the entrance. The first day, this 240-pound kid was in there playing. We heard this grunt and a crack. He had fallen through the booth, and it started falling apart. We spent until 2 a.m. rebuilding. By the next morning, the wind had lifted the booth and slammed it against the wall. I wrote the show off, but that day I met a guy who bought $400,000 worth of systems, our largest sale ever."
