Like any "act" who gets booked to perform, Lil Wayne got a guarantee. He wasn't playing for the door money- he was guaranteed a certain amount of money to perform, no matter who/how many showed up. When he saw that no one came to the show, he cancelled on his few fans. Shows you what a professional Lil Wayne is. He was going to rap or lip-sync over a tape, which is basically karoke- not much in the way of overhead costs (no band to pay, etc.) A lesson for the kids who showed up: next time, chose to support a REAL artist, rapper or musician. Believe me, three years from now you couldn't get $2 for a used Lil Wayne CD.
