A random story:
When I was in my early 20's, I was visiting a friend in Indianapolis and we were driving past what was then referred to as the "Hoosier Dome". (Many of you probably remember this)
There was a music festival going on that day/night and I wanted to check it out so we parked and walked up to the door to try and purchase a bracelet that would gain us entry to the festival. They told us they were sold out and that we should have reserved our tickets long beforehand.
